Dorabella glanced at the papyrus, and then read: "Different colors of light have different refractive indices. Under the refraction of the triangular lens, the sun's light will become a real seven-color light. Rainbow after rain. , Is the reason why sunlight is refracted."

　　 "The rainbow in the sky seems to have seven colors, but what is it that refracts the sunlight?"

　　 "What is a triangular lens?"

　　"..."

　　 There was a lot of discussion, and Dorabella was a little guilty at first, but soon held up his head.

　　 He didn't believe that Li Wei could really make the sun into seven colors. As long as Li Wei could not make the sun into seven colors in front of him, he would not believe it if he talked too much.

　　 "Triangular lens is this thing, everyone can take a look."

　　 Li Wei took out a triangular lens and said.

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

　　Blowing glass is actually very simple, just use a long hollow iron tube to blow out the shape you want.

　　 Sura they looked at this triangular lens curiously, could it be that this thing really divides the sunlight into seven colors.

　　 Li Wei looked at Dolabella with a playful look. Dolabella was a little guilty, but he soon raised his chest and raised his head. He was not afraid. He didn't believe that the sun was really composed of seven-color light.

　　 "Let's do an experiment below to see if the sunlight is really composed of seven-color light."

　　 Li Wei said with a smile.

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

　　 Sunlight shines on the triangular lens, and then is refracted on the classroom wall, exuding seven fascinating brilliance.

　　Looking at this scene, many people were shocked and dumbfounded.

　　 "Miracles!"

　　 Sura said with a shocked face.

"This is impossible!"

　　Tulius was so surprised that he couldn't close his mouth.

　　 "Red, orange, yellow, green, blue, ingot, purple, it really is seven colors of light."

　　 Someone said.

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

　　 "Dora Bella, in view of your repeated violations of class 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 am a deputy, why would you expel me from the class."

　　Dora Bella said arrogantly.

　　 Li Wei looked at this guy angrily. You, a lieutenant, ran here to help you. This is not the place where you came to run wild.

　　 "Dora Bella, you should go outside for the class first."

　　 Sura said.

　　 Seeing Sura speaking, he could only say aggrieved: "Okay."

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

　　 Forget it, I bear it. Arguing with this fool, his IQ will be reduced to the same level, and then Dora Bella will use his rich experience to defeat him.

　　 "What refracts the rainbow in the sky?"

　　 Sura asked suspiciously.

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

　　……

　　 This class made everyone listen to the heavenly scriptures, breaking the worldview of how many people do not know.

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

　　Because the microscope has not been made, they still cannot see the microorganisms, but this does not affect the use of the magnifying glass.

　　 They also asked many other questions, but Li Wei did not answer any questions that were not related to medicine.

　　What a joke, knowledge is wealth and knowledge is power.

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

　　 In case of a knowledge explosion, how could he rely on his knowledge to lead the world so far?

　　 Even though Li Wei has always cherished himself, the class he taught is still thoroughly famous.

　　 After returning home, Tulius looked desperate.

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

　　 Old Turius said while lying on the bed.

　　 "All right, Dad, do you know that sunlight is formed by seven colors of light?"

　　 Turius asked.

　　 "How is this possible? What's wrong with you, is there anything uncomfortable?"

　　 Old Turius asked.

　　 "Did you know that light reflects and refracts?"

　　 Turius asked.

　　 Old Tulius looked at Tulius with a worried look. Levy wouldn't have done any witchcraft on him, right?

　　 "Did you know that water will evaporate to form water vapor, and then rain will form in the sky?"

　　 "What the **** is wrong with you, don't scare me."

　　 Old Turius said with a horrified expression on his face.

　　 "Dad, I want to go to the school to attend a class."

　　 Tulius said.

　　 "No, I firmly oppose it."

　　 Old Turius said.

　　 After a long time, I became like this. Wouldn’t I become a lunatic after going to class?

　　 "Look at this."

　　 Tulius gave a roll of papyrus to the old Tulius.

what is this?

　　 After reading it, the old Tulius fell into deep thought.

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

　　 "Today, Li Wei used the three-edge realm to turn the sunlight into seven-color light, and everyone saw it. Including Sula and the others?"

　　 Tulius said.

　　 "What did you say? This is impossible!"

　　 Old Turius looked shocked.

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

　　 Tulius said.

　　 Old Tulius was speechless for a long time. If this is true, then the matter is big, and Levy is probably really a great philosopher.

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

　　 Old Turius thought for a while and said.

　　 "Thank you father."

Metella returned home happily~www.readwn.com~ She wore Li Wei and sent a cotton-padded coat to go out to the house of her best friend, Mrs. Metlue, and found that the dress was really soft and warm, not only did not affect the activity , And also press shoulders like a blanket.

　　 Even her girlfriends repeatedly praised her, which made her feel very good today. At this time, she found Sura holding a piece of glass and looking at a roll of papyrus.

　　 "What are you doing?"

　　 Metella asked.

　　 "I am reading a book written by Li Wei."

　　 Sura glanced at her and said.

　　 "Li Wei actually wrote a book?"

　　Metera said with a shocked look.

　　 Li Wei has just grown up this year, so he has already written a book.

"let me see."

　　 Metella walked over and said.

　　 "The human body includes a large number of cells. What are cells?"

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

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