I Made Scientific Magic

  Chapter 502 Photoelectric effect and the world is fluctuating!

  After Jeffrey spoke, the apprentices immediately got busy.

  With the help of magic, it is very easy to make a simple improvement to the bezel, and it takes only a few minutes before and after.

   The baffle changed from one hole to two holes, and its shape changed from round to square.

  When a strong beam of light shot out from the launcher and penetrated through two extremely fine gaps, the faces of everyone present showed expressions of astonishment.

  Because nine relatively clear rectangular light spots appeared on the black wall behind the hole, the light spot in the middle was the brightest, and the brightness of the light spots on the other two sides gradually decreased.

   "Why are there so many spots?"

The apprentice who proposed just now was stunned. If the light really travels along a straight line, then after a beam of light passes through two holes at the same time, only two corresponding shapes should appear on the wall. The same light spots and stripes as the holes are right.

  Even if the light is refracted after hitting the object, such a strange phenomenon should not occur—not to mention that the brightest light spot is actually located in the center of the two holes, which is completely unreasonable.

  This discovery also surprised Jeffrey. He had vaguely realized something in his mind, but he couldn't think of the key point.

   "It's like water waves..." A short wizard next to him muttered to himself.

  Jeffrey was stunned for a moment, then turned his head, grabbed the wizard by the collar, and asked excitedly. "Water wave? What water wave?"

  The short wizard was taken aback by Geoffrey who suddenly became extremely excited, and stammered in response. "It's the ripples of water, teacher..."

"Demonstrate it to me, the water wave you just mentioned...now!" Jeffrey released the wizard, grabbed a water basin with the [Mage Hand] and put it on the table, saying excitedly .

The short wizard did not dare to neglect at all, took a double-hole baffle in the laboratory, put it into the water basin, and left it for a few minutes. Reach out and touch the water.

   "Like this!"

  Under the eyes of everyone, waves of water spread from the finger as the center to all directions, and soon touched the gap in the baffle.

  After the vibrating water wave passed through the gap, it immediately split into two new ripples and began to spread toward the inside in a semi-circular shape with the gap as the center.

  Because the distance between the two gaps is very close, the generated water waves collided quickly, and began to interfere with each other, cancel or merge.

"It's the peaks and troughs... so it's like this, so it's like this!" Jeffrey understood the moment he saw the water waves, and a look of great surprise appeared on his face, no wonder he felt a sense of familiarity just now, because this is the same as The ripples created by using force magic to stir spacetime are very similar.

  At this moment, he seemed to have seen a corona medal waving to him!

   "Teacher, what's going on?" The faces of the apprentices beside him were full of puzzled expressions. They didn't understand at all, and they didn't quite understand why Jeffrey became so excited.

   The excitement in Jeffrey's heart was uncontrollable, and he immediately explained to the apprentices. "You can regard the ripples spreading on the water surface as light rays, which is easy to understand..."

  Water waves create ripples on a calm lake.

   Some places will be raised, which is the crest, and some places will be sunken, which is the trough.

  If two ripples of equal intensity appear at the same time as just now, they will interfere with each other when they meet.

  When the crests of two ripples meet, the resulting interference wave will become stronger than before, and when the trough meets the trough, the water surface will sink deeper due to the superposition of the two troughs.

   In addition, there is another situation where when the crest of one wave meets the trough of another wave, the two cancel each other out.

  The same is true for light. When a beam of light passes through two cracks, it will also interfere with each other, so it will produce a strange scene of alternating bright and dark light.

  The bright place is the crest, and the dark place is the trough...

  Under Jeffrey's explanation, a group of apprentices quickly looked at the water wave, and soon found that after the two water waves collided, the place where the wave crest appeared was exactly the direction where the previous light spot was lit, and the two were almost exactly the same!

   "In this way, the phenomenon of light scattering and reflection is also explained. Look at those water waves. After hitting an object, the force will be weakened and then bounce back..."

  The more Jeffrey talked, the more he felt that his light wave theory was perfect, and it could completely explain every natural phenomenon of light.

"So light is by no means composed of tiny light elements. Its essence is a kind of wave, just like the ripples produced by stirring space and magnetic fields, it is a continuous and indivisible existence!" Jeffrey resolutely said concluded.

   This is definitely a research result that can shock the entire magic world and decipher the essence of light!

  The wizards and apprentices gathered around Jeffrey were equally excited.

It is conceivable that three months later, when they presented this theory at an academic seminar, what a storm it would be. Their teacher Jeffrey would undoubtedly be able to win a Corona Medal, and their support staff might also be able to get it. A Morning Star Medal as a reward.

  This is a great honor!

  While the wizards of all schools were happily flattering, some people made a worried suggestion. "Teacher, do you want to publish some of the results first? I heard that many schools of thought are studying optics. Since we can discover this phenomenon, others may not have thought of it."

  Hearing the words, Jeffrey immediately became vigilant, and hurriedly said something. "You're right. I'm starting the draft now. You guys should sort out the research notes of these days as soon as possible. It's best to sort out the paper before noon."

"And help me find the editor of Magic Daily, Luo Er. I remember that he recently stopped in the city of fire oil. If he is fast enough, he might be able to catch up with the release of Magic Daily tonight!" Jeffrey said He spoke quickly and ordered.

This experiment is actually not difficult to do, and the water wave theory is not too difficult to think about. Jeffrey is very clear that the reason why he was the first to discover it is entirely due to the fact that he stayed in the rear to extract deuterium and tritium elements. There is plenty of time for academic research.

   Now that the war against the empire is coming to an end, everyone has freed up their time. If we wait until the academic seminar three months later, who knows if someone will cut us off.

   In short, let’s release some research results first, and then take a seat. We must not let others take this honor away first!

Jeffrey worked hard, spent several hours, and successfully finished the thesis before noon. His mood immediately became extremely good, and he distributed ten magic gold coins to each of the wizards in the laboratory as a preliminary rewards!

  As for the few wizards who reminded him, Jeffrey even patted his chest and promised that he would definitely ensure that they would get a Morning Star Medal!

"Anthony and the others should still be studying the changes of magnetic and electric fields, right?" Jeffrey thought proudly. There were three great wizards over there, and they hadn't figured out the electromagnetic field until now, so he went first. One step to understand the nature of light.

   Jeffrey is looking forward to what kind of expressions they will have after the release of today's Magic Daily.

  At the same time, in the city of fire oil, the great wizard Anthony and others whom Jeffrey had been thinking about were pacing anxiously in the laboratory, staring at the four exquisite formulas in front of them from time to time, frowning and thinking.

  These formulas are exactly the Maxwell equations written by Lynn himself in the small universe!

  At the beginning, Anthony felt that these four formulas were extremely profound. After in-depth research, he was even more surprised to find that these are simply the bible of thunder magic!

   Disassemble each formula, and the calculations are enough to cover several pages. Their research and experiments on electric fields and magnetic fields are also sufficient to prove the accuracy of these calculations.

  According to some thunder wizards - the truth is jumping off the page in a wonderful way!

   Now what they are exploring is the propagation speed of lightning in different media.

  Like light, the speed of thunder is extremely fast, and the speed of propagation in the air can even reach tens of thousands of kilometers per second!

   But this is obviously not the limit!

After experimenting with dozens of different substances, Anthony found that the speed of lightning propagation on the conductor is extremely fast. In order to conduct an accurate experiment, they produced several conductors with a length of ten kilometers and made of different materials. , Prepare to use practice to demonstrate how fast it is.

  This experiment should have results today!

  Just as Anthony's mood became more and more impatient, the closed laboratory was finally opened, and dozens of Thunder wizards entered in a single file, one of them said happily.

   "The experiment has been tested, Master Anthony."

   "How fast is it spreading?" Before Anthony could speak, the Thunder wizards on the side eagerly asked.

   "It's 299,000 kilometers per second!" The man replied.

   "299,000 kilometers..." Anthony kept murmuring, why did this speed sound so familiar.

   "Are you sure you are not mistaken? Isn't that about the same as the speed of light?" Witch Fulla said in a daze.

   "Of course there is no mistake, we have tested it hundreds of times!" The great wizard Sanchez rolled his eyes. The speed of current propagation in each conductor is the same, but due to the problem of resistance, the final intensity of the current passed is different.

  In order to ensure its accuracy, Sanchez even did it himself, relying on the great wizard's excellent perception and computing power to judge the moment when the current arrived.

  After dozens of times in a row, he was almost paralyzed by electric shock, so he was extremely sure that this value was absolutely correct!

   "But...how could it be such a coincidence?" The wizards present looked at each other in blank dismay.

Last time they relied on the gear rotation test to find out that the speed of light was 299,520 kilometers per second. There will be slight errors during the test.

  Anthony never believed that this was just a coincidence, and there must be a deeper relationship between the two.

   This point, he had already noticed when he was studying Maxwell's equations.

  Suddenly, Anthony suddenly seemed to think of something, suddenly pointed to Maxwell's equations on the table, and shouted excitedly. "I understand... light is electricity, light is electricity!"

   "Light is electricity?" Sanchez frowned involuntarily. Although the speed of electric current in a conductor is similar to that of light, we can't draw conclusions so arbitrarily, right?

   One must know that the propagation speed of thunder in the air is much lower than that of light. For example, they can barely sense electric current, but they cannot sense light elements at all!

  Anthony explained in an extremely fanatical manner. "Listen to me, light may be electricity in another form, the relationship between the two is like the magnetic field and the electric field!"

   "Like the electric lights all over the city of fire oil, after the electricity enters the wick, it is consumed in the form of light, or in other words, the electricity is converted into light and radiates out!"

   "If my guess is correct, electricity can be converted into light, and the gathered light beams can also be converted into electric current!" Anthony patted the table excitedly.

   "Quick, experiment now!"

  Hundreds of Thunder wizards immediately got busy. After trying countless materials for a whole night, they successfully made a simple solar device!

  As Anthony thought, after the light beam irradiated the device, it was continuously transformed into electricity!

   Witnessing the successful start of the motor, the whole laboratory erupted into loud cheers and applause.

   "Teacher, you are right, light is electricity, and electricity is light!" Fulla is also honored, it seems that they have decided on the corona medal for understanding the essence of light!

   Sanchez added on the sidelines. "I dare say that light is mostly tiny electrons. Lightning is like those radioactive elements. After being excited, it will continuously throw its own energy around until it is exhausted."

   "What a wonderful idea, it seems that we will be able to find out the light particles, or the smaller electric elements in a short time!" Anthony said appreciatively.

  This discovery will definitely detonate the entire magic world, and their names will definitely be engraved in the history of magic!

  However, when everyone was rejoicing, the door of the laboratory was knocked open.

  Anthony turned his head rather dissatisfied, and found that the person who pushed the door in was another disciple of his own—Kagal.

  Gripping a few pages of newspapers in his hand, he said pantingly after hastily entering the door. "Teacher, please take a look at today's Magic Daily. The great wizard Jeffrey said...he has successfully deciphered the essence of light!"
