Dorabella glanced at the papyrus, and then read: Different colors of light have different refractive indices. Under the refraction of the triangular lens, the sunlight will become a real seven-color light. The rainbow after the rain , which is why sunlight is refracted.”

The rainbow in the sky seems to be indeed seven colors, but what refracts the sunlight?

What is a prism?

...

Everyone was talking about it, and Dolabela was a little guilty at first, but she quickly straightened her head.

He didn't believe that Li Wei could really make the sun into seven colors, as long as Li Wei couldn't make the sun into seven colors in front of him, no matter how fancy he said, he wouldn't believe it either.

The triangular lens is this thing, everyone can take a look.

Li Wei took out a prism lens and said.

It is not easy to make this thing, but fortunately, Li Wei has been thinking about making mirrors, so he bought a glass workshop and used the glass blowing method to blow out a few.

Glass blowing is actually very simple, just use a long hollow iron pipe to blow out the shape you want.

Su La and the others looked at the triangular lens curiously. Could it be that this thing really divides the sunlight into seven colors.

Li Wei looked at Dolabela playfully. Dolabela was a little guilty, but he quickly raised his chest and raised his head. He was not afraid. He didn't believe that the sun was really composed of seven colors of light.

Next, let's do an experiment to see if sunlight is really composed of seven colors of light.

Li Wei said with a smile.

After speaking, he took the prism and walked to the door, then stretched out the prism to adjust the angle.

The sunlight shines on the triangular lens, and then is refracted onto the walls of the classroom, emitting seven charming brilliance.

Seeing this scene, many people were stunned with shock.

miracle!

Sura said in shock.

This is impossible!

Tullius couldn't close his mouth in surprise.

Red, orange, yellow, green, blue, ingot, and purple are indeed seven colors of light.

someone said.

Everyone is talking about it, how is this possible? How can sunlight be composed of seven colors of light.

Dolabella, in view of your multiple violations of classroom discipline and making loud noises in class, I announce that you will be expelled from class.

Li Wei said with a sneer.

You can't do this. I'm the lieutenant general. Why do you expel me from the classroom?

Dorabella said arrogantly.

Li Wei looked at this guy angrily, what a lieutenant you are doing here, this is not the place for you to act wildly.

Dolabella, you should go outside and listen to the class first.

Sura said.

Seeing that Sura had spoken, he could only say aggrievedly: Okay.

After finishing speaking, he left the classroom, went outside and leaned half his body into the window, looking at Li Wei triumphantly.

Forget it, I'll bear it. Arguing with this fool will bring his IQ down to the same level,

Then Dolabella will beat him with his vast experience.

What is the refraction of the rainbow in the sky?

Sura asked suspiciously.

Li Wei thought for a while, let's explain.

...

This class made everyone feel like listening to a book from heaven, and broke the worldview of an unknown number of people.

Li Wei explained the transformation of water and gas, the principle of rainbow formation, and the concept of high-temperature disinfection.

Since microscopes have not yet been made, they still cannot see microorganisms, but this does not affect the use of magnifying glasses.

They also asked many other questions, but Levy did not answer any questions that had nothing to do with medicine.

Are you kidding me, knowledge is wealth and knowledge is power.

Li Wei has a deep understanding of this, and he will not teach those people that knowledge.

In case of a knowledge explosion, how could he be far ahead of the world with his knowledge.

Even though Li Wei has always cherished his broom, the class he gave was completely famous.

After returning home, Tullius looked devastated.

Why do you look like this, today is going well.

said old Tullius lying on the bed.

It's all right, Dad, did you know that sunlight is made up of seven colors of light?

asked Tullius.

How is this possible? What's wrong with you, is there something wrong?

asked old Tullius.

Did you know that light reflects and refracts?

asked Tullius.

Old Tullius looked at Tullius with a worried look on his face. Li Wei probably cast some witchcraft on him.

Did you know that water evaporates to form water vapor, which then forms rain in the sky?

What's wrong with you, don't scare me.

Old Tullius said with a look of horror.

Dad, I want to go to the academy to attend classes.

said Tullius.

No, I firmly oppose it.

said old Tullius.

After going for half a day and coming back like this, wouldn't it be crazy to go to class again?

Look at this.

Tullius gave the elder Tullius a roll of papyrus.

what is this?

After reading it, old Tullius fell into deep thought.

This thing looks extremely complicated, but it makes some sense when you think about it. Is it true?

Today, Li Wei used the triangular prism to turn the sunlight into seven-color light, and everyone saw it. Including Sura and the others?

said Tullius.

What did you say? It's impossible!

Old Tullius was shocked.

I have seen it with my own eyes and heard it with my own ears. And Sykes, Vitius and the others have seen it. If you don't believe me, you can ask them.

said Tullius.

Old Tullius was speechless for a long time. If this is true, then things will be a big deal. Li Wei may really be a great philosopher.

Since you want to go, I won't stop you.

Old Tullius thought for a while and said.

Thank you father.

Metela returned home happily. She wore the cotton padded coat that Levi sent and went out to the house of her best friend, Mrs. Mettle Road. She found that the clothes were really soft and warm. shoulder.

Even her girlfriends praised her repeatedly, which put her in a good mood today. At this time, she found that Sura was looking at a roll of papyrus with a piece of glass.

What are you doing?

Metela asked.

I'm reading a book written by Li Wei.

Sura glanced at her and said.

Li Wei actually wrote a book?

Metela said with a look of shock.

Li Wei has just come of age this year, why has he already written a book.

let me see.

Metela walked over and said.

The human body actually contains a large number of cells. What are cells?

Human blood is mainly divided into four categories. We divide them into A, B, AB and O. In addition, there are some rare blood types. Blood of the same type can be transfused with each other, but sometimes May cause rejection.

A person with AB blood type can receive blood transfusions from the above four blood types, and is called a universal recipient. But his blood can only be transfused to people with AB blood type.
