I Made Scientific Magic

  Chapter 509 The terrifying double-slit interference experiment

  After Lynn announced that the seminar was over, the wizards who walked out of the exhibition hall still failed to recover from the dispute between light waves and light particle theory.

   "Do you really think that volatility and particle can exist at the same time?" "This is simply nonsense. How is it possible for a thing to be both continuous and dispersed?"

"This is from the mouth of Speaker Lynn, the star of magic. If he is not fully sure, who would destroy his reputation in a seminar with tens of thousands of people?" Raphael interrupted the debate among the crowd. The research of a magic star is very trustworthy.

   "So what if it's a star of magic? Doesn't it make mistakes if it is famous?" A great wizard from the empire said with a sneer, as long as it is an individual, there must be negligence.

  Optics has only been established for more than a year, and no one dares to say that they can fully understand it.

  Compared to the debate among ordinary wizards, Anthony looked at the disclaimer in his hand and remained silent for a long time.

  The above content is very brief, it means that those who signed the agreement voluntarily bear all the consequences of listening to the quantum theory, but... the meaning behind this is chilling.

   "Teacher, should we sign or not?" Fulla asked hesitantly, with a slightly worried look on her face.

  She doesn't have Anthony's firm belief, so she has long lost the ability to perceive electric charges. She has a deep understanding of [Spellcasting Obstacles], and she can't help but flinch a little.

   "Sign, of course you have to sign!" Anthony said without hesitation.

  He believes that his research is absolutely correct, light is a wave, and it is an electromagnetic wave!

  Anthony's fingertips lit up with a touch of magical fluorescent light, and signed the disclaimer as ink, and then handed it to Fulla, asking her to hand it to Lynn.

   "Yes, teacher!" Seeing that Anthony had made up his mind, Fulla didn't say any more, and signed her own disclaimer, and then returned to the exhibition hall with two statements.

   After Fulla left, Anthony closed his eyes. After about two or three seconds, he suddenly breathed a sigh of relief, his expression relaxed a lot... He can still use lightning spells, which is very good, very good!

   On the other side, Fulla, who came to see Chairman Lin En, hit a wall, because there were too many people who wanted to find this magic star.

   There is a good relationship, Rafael and others who came here to discuss the theory of optoelectronics, and some wizards who have prepared generous gifts and plan to have a relationship with the new speaker, plus them who came to submit the disclaimer, it is a mess!

   is worrying about how to launch a single particle Lynn, so of course he won’t spend his time and energy here at this time, in the name of making experimental equipment, he will shut himself behind closed doors.

  Even the requests from several speakers were no exception—Lynn directly gave them several research manuscripts and dismissed the matter.

  Micro and macro are completely two sets of theories. Explaining them one by one is not only time-consuming and laborious, but the other party may not be able to understand them. It is better to wait for tomorrow's academic seminar to explain them together, so as not to repeat the explanation several times.

  Jonny and Aylock stood guard at the door, apologetically telling everyone who wanted to meet that Speaker Lynn was preparing for tomorrow's seminar, and accepted the disclaimer they brought.

  The efforts of the two also allowed Lynn in the room to relax, and began to think about how to emit particles.

  In the beginning, his goal was to use alchemy to reproduce the federal microparticle extraction device, but it took half a month to find that it was too difficult, even if he could control it at the atomic level.

   But it’s normal to think about it. In addition to using a strong magnetic field, this thing also uses quantum technology...

  So Lynn can only consider some relatively old methods-such as thermal field emission electron guns!

  …

   One night passed in a blink of an eye.

   It's just that this night is not peaceful, and not many people can sleep well.

   Fortunately, as a wizard, staying up all night is nothing. Sometimes it is very normal to fight for a few days in order to specialize in a spell. Almost the next morning, the large exhibition hall is already full of people.

  Anthony has also arrived, and his eyes have swept across the rows of large exhibition halls. Only about 30% of the seats are empty. It seems that not many people are scared off by the disclaimer.

   But that's right, the debate about the nature of light will be decided today. As long as wizards still have the desire to learn, they will never let go of this opportunity.

  As for those who flinched, Anthony was very disdainful, and lost their faith in pursuing the truth, and their magic path may have come to an end!

  About eight o'clock in the morning, all the speakers had already arrived, and Lynn was no exception. By the way, he also asked Eloke and others to carry his experimental device out.

   "Isn't that my double-slit interference experiment?" Jeffrey said in surprise.

  Anthony and others also recognized it, after all, the two are so similar.

   are all emitting devices on the left, partitions in the middle, and photosensitive screens on the right.

   Under the discussion of everyone, Lynn also nodded. "That's right, this is exactly the double-slit interference experiment. To be precise, I have modified it to a certain extent!"

   "The device on the left, I call it a thermal field emission electron gun, consists of five parts: filament, cathode, grid, anode, and deflection coil..."

  With a wave of his hand, Lin En split the shell with great precision, but did not damage the internal structure at all, and then explained its working principle to everyone.

  The so-called filament is not the hair of the fire lion, but a tungsten wire. After it is electrified, it will convert electrical energy into heat energy and heat the cathode, thereby releasing and emitting a large number of electrons.

  These electrons will be blocked by the grid, and the number of electron beams passing through can be controlled by adjusting its relative position to the cathode, and finally accelerated under the electric field generated by the anode, and the orientation is adjusted by the deflection coil, and finally the electrons are emitted one by one.

Lynn's explanation was very professional. Many of the wizards present were confused. Fortunately, they understood the last paragraph. The star of magic found a way to emit a single electron, and prepared to use it to to experiment.

   "But... shouldn't it be photons?" A young witch whispered.

   The voice was very soft, but none of the wizards present could see clearly.

  Lin En rolled his eyes, emitting a single photon is more troublesome than electrons.

   "It's okay, it's all the same!" Lin En said with a smile. They are both microscopic particles, and they all have quantum phenomena.

   After Lin En explained a sentence, he stopped talking, looked at the crowd and spoke again. "My experiment is very simple. I use an electron gun to shoot electrons into the double slit one by one, and then observe its distribution image through the special fluorescent screen behind it..."

   "What do you think will happen when particles pass through the double slit one by one?" Lynn asked suddenly.

  The wizards present pondered for a while, and soon came to a conclusion, and Glenn was the first to say it. "It should be like a small hole imaging, and the corresponding image will be mapped in the rear!"

   "Let's try it!" Lynn didn't agree or disagree with Glenn's words, and directly activated the thermal field emission electron gun. Under the attention of everyone, the tungsten wire was heated and lit up...

  Under the invisible microscopic field, one after another, the accelerated electrons slammed into the front at an extremely fast speed.

  Because the holes are very small, it is not easy to pass through, so most of these electrons are hit on the partition.

   After waiting like this for about five seconds, Harov said solemnly. "It passed!"

   Allard and the others widened their eyes, staring intently at the light-sensitive screen behind the partition, and then realized that a small, undetectable dot suddenly lit up on it.

   This means that Lynn's thermal field emission electron gun successfully sent a single electron to the special photosensitive screen at the rear.

As time progresses minute by minute, the light spots on the photosensitive screen are becoming more and more dense, but instead of the reflection of two gaps as they imagined, the light spots are roughly distributed in nine In the area of ​​a strip...Although there are light spots in the rest of the area, the number is very small.

   "This is... this is interference fringes?!" Anthony looked at the scene in front of him with a look of astonishment on his face.

  The rest of the wizards were equally unbelievable, and even the great wizards in the front row could not help but move a few steps closer to confirm that it was not an illusion at a close distance, and there was nothing wrong with their eyes.

   "Strange, why is this happening?" Vittorio frowned and muttered to himself.

   "Hahaha, light particles are right, my light particle theory is right!" Sanchez shouted excitedly, which shows that particles can also produce fluctuations!

   "Idiot!" Anthony directly interrupted Sanchez's words. "If the electrons really pass through the hole one by one, what affects its trajectory?"

Sanchez's laughter stopped abruptly, and he was obviously aware of this. His previous particle scattering experiment was successful because of the advantage of quantity. By letting the particles in the two exploding element clusters collide with each other, he simulated a similar fluctuating path.

  The current situation is different. The electrons pass through the gap one by one. Normally, they will not receive any interference. However, the fact is that these electrons have deviated from the original direction.

   It seems that there is a mysterious force that makes these electrons fall to these fixed points in the path of waves.

   There was a chill behind Sanchez, what is affecting these microscopic particles.

"Could it be that there is something wrong with the electron gun? In fact, the electrons fired at a time are not just one, but many..." A great wizard suddenly thought of this, but under the gaze of all the wizards, his voice became louder and louder. The smaller it was, the more it was interrupted directly.

   After all, this is an experiment to question the magic star face to face.

  However, in the eyes of people, it is indeed a method of explanation, assuming that many electrons pass through the hole, and then they affect each other.

  Although such a guess is outrageous, and it cannot explain why only light spots light up one by one on the photosensitive screen, and why the electrons happen to be on the same path as the wave trajectory, it is barely an explanation.

"Since everyone has doubts, why don't you all enter the magic net, and I'll take you to 'take a look' for yourself?" Lynn said with a smile, and then he connected his recently developed The spell of the magic net was announced.

   This is a very simple psionic magic, the difficulty is not high, as long as it is an official wizard level, it can be used.

  In just a few minutes, the wizard in the exhibition hall has mastered this magic.

  The reminder sound from Zhinao resounded in his mind, and more and more people connected to the magic net.

  Even though most of the wizards have just connected to the magic net and can mobilize very little computing power, they still can't stand up to the crowd, and still 'support' Lin En...

  The level of mental power has also been increased from seven to eight.

  His soul strength can't keep up with the rapid growth of computing power.

   It took Lynn more than ten seconds to get used to it, and then he expanded his domain, including the entire exhibition hall. Under the link of the magic net, all the wizards present temporarily gained the ability to perceive electromagnetic fields.

  At the same time, within a tenth of a second, the thermal field emission electron gun fired another 'one' electron.

  Glenn, who was staring at the experiment in the front row, instantly sensed the disturbance of the electromagnetic field. This disturbance is very small, but under the huge computing power provided by the magic net, it is extremely clear.

   This 'electronic' was very lucky to pass through the gap on the right and hit the photosensitive screen, and a tiny light spot lit up at the corresponding position on the screen.

   "Really, there is really only one electron!" Anthony was extremely confused. Although they didn't really see or sense the electron itself, they observed a rough trajectory through the disturbance generated by this thing.

  Particles do travel in a straight line, and the light spots on the rear photosensitive screen are also solid evidence.

  But why there is such a weird interference fringe similar to that produced by fluctuations?

  The wizards, who were as puzzled as Anthony by this, all raised their 120 points, and they wanted to see with their own eyes what actually affected the trajectory of the electron.

  The thermal field emission electron gun fired non-stop. Under the "close watch" of Anthony and others, every lucky "electron" passed through one of the gaps faithfully, without the slightest change in the path.

  What about the agreed deflection?

  Continuing this way, how do the light spots similar to interference fringes form?

  Anthony's expression became more and more confused, and at this moment a burst of exclamation suddenly sounded in the exhibition hall.

   "Look, the photosensitive screen... the photosensitive screen... has changed!"

  Anthony's pupils tightened, and he noticed that at some point, the pattern on the screen had gradually changed from nine stripes to two...

Seeing such a scene, even Harov, Vittorio, and Aurora couldn't sit still. The six eyes fixed on the changing photosensitive screen, and then turned to sit quietly on the judge's seat Lynn.

   Lynn shrugged and said very calmly. "As you can see, my electron launch gun is placed there, and no one has touched it!"
