"Mo Zhong, come here!"

Li Zexuan, who was about to play a new game, did not act immediately, but instead summoned Mo Zhong, who was stunned next to him.

"exist!"

Mo Zhong quickly recovered from the shock, ran to Li Zexuan's side, bowed his waist, and made a gesture of listening.

I saw Li Zexuan leaning into Mo Zhong's ear, whispering something, and then...

"Ah? Chief! This... you're not kidding me, are you?"

Mo Zhong stared, and his mouth was open enough to stuff an egg.

"Who has time to joke with you? Why don't you go!"

Li Zexuan said angrily.

Everyone off the field was a little stunned when they saw this. They didn't know what Li Zexuan ordered to make Mo Zhong have such an expression.

However, their doubts did not last long. After Mo Zhong ran out, it took about half a cup of tea to touch the tea. When everyone noticed the change, they suddenly exclaimed!

Because Mo Zhong actually ran to the roof and uncovered the tiles!

There is a saying that goes, if you don't fight for three days, and you go to the house to uncover the tiles, the teachers and students off the court couldn't help but wonder in their hearts: "What did Mo Zhong get out of his mind?" How dare you run to the roof to uncover the tiles?

"Sir, can you take this piece off?"

Mo Zhong on the roof leaned down and shouted down.

"Om~!"

Only then did the students and teachers in the auditorium understand that Li Zexuan had just ordered Mo Zhong to go to the house and uncover the tiles! They couldn't understand what Li Zexuan's actions meant, and couldn't help but talk a lot below.

"No! Go a little further back!"

I saw Li Zexuan glanced sideways, and then replied.

The Mo Zhong on the roof had to cover the uncovered tile, then opened another piece, and asked, "Shan Chang, is this okay?"

"That's it!"

"Then...then I'm going down!"

"Stay on it first, I'll need you later!"

The bizarre conversation between these two people was a shock to everyone's attention. Fortunately, after saying this, Li Zexuan finally became "normal". He dug out a piece from a box on the lecture table. The bright triangular colored glass then said to everyone off the field:

"Does anyone know what color sunlight is?"

(About optics, the first volume of the "Physics" textbook of the academy did not mention it)

"Is that even a question? Sunlight must be white!"

As soon as the words fell, Cheng Chumo couldn't help laughing.

"It's obviously red! The sun is so red in the morning, how could it be white?"

Another student immediately retorted.

"What red? It's obviously yellow, can't you tell the difference between red and yellow?"

After a while, there was a commotion off the court. Li Zexuan coughed twice and said, "Okay, be quiet! Don't argue, I'll show you what color the sunlight is!"

The students immediately quieted down, holding their breaths and staring at the podium!

Li Zexuan first erected a stand on the podium, with white paper pasted between the stand (as a white screen), and then he used the side of the triangular colored glaze to face the sun (at this time, everyone understood that Mo Zhong ran to the roof to uncover the tiles. For what, it turned out to be to attract sunlight), a magical scene appeared!

"Okay, did you see anything?"

Li Zexuan pointed at the white screen on the podium and smiled.

"Wow~!"

The teachers and students were in an uproar. They actually saw a colorful light spot on the white paper. Isn't this a rainbow?

"Rainbow? It's not raining, where did the rainbow come from?"

"Yes! Is it still sunny today?"

"A miracle! The mountain chief can actually create a rainbow?"

"No! The mountain chief should be trying to tell us that the sun's rays have seven colors!"

"How is that possible? Why is the sunlight I see white?"

"What white? It's obviously yellow!"

"Red!"

The students were amazed for a while, and then a few started arguing again. Li Zexuan said: "Everyone is quiet! Through this little game, I just want to tell you that many times what you see with your own eyes may not be true! For example, sunlight, some of you think it is white, red, yellow, or transparent, but in fact? It is composed of seven colors mixed together!

For another example, have you ever thought about what kind of substance light is? Is it as ethereal as sound, or is it a real substance like the rice and flour we eat? "

When everyone heard this, they fell into deep thought.

After a long while, a relatively thin student who also looked very young stood up and asked, "Student Li Yan, ask Shan Chang, what is light?"

Li Yan, this is Li Chunfeng's son!

Li Zexuan's heart moved. He had seen Li Yan on the transcript of the entrance examination and knew that this kid was Li Chunfeng's son, but this was the first time he had seen Li Yan.

only.....

"Haha! That's a good question! But let's put this question aside for now, and then I'll show you a little game!"

But it was Li Zexuan who showed a faint smile again, and then said "cheaply".

Li Yan: "￣へ￣......"

Even as a Taoist, Li Yan, who had cultivated his self-cultivation for many years and was quiet and inactive, could not help but jump at the moment. He opened his mouth, thinking... He wanted to make a few swear words, but he still sat back after thinking about it. .

Even for him, let alone the rest of the students!

"Captain, please explain it to us first!"

"That's right! Let's make it clear before making the game!"

"Cao, it's like this again! You know how to make games! Make your sister's games!"

Li Zexuan's face turned pale, he pressed his hand down, and said, "Everything is quiet! Good meal is not afraid of being late, and I can't eat hot tofu in a hurry. What are you in a hurry for? Show me all of it, and study hard!"

Seeing that Li Zexuan was about to get angry, the students wisely shut their mouths.

"Mo Yun, take this thing to Mo Zhong!"

At this time, Li Zexuan took out a wooden board (there was a small hole in the wooden board), handed the wooden board to Mo Yun, and ordered.

Afterwards, he instructed the students to close all the curtains (this auditorium has glass windows). At this time, Mo Yun had already brought the planks to the roof and handed them over to Mo Zhong.

"Mo Zhong, cover the hole in the roof with a plank!"

Li Zexuan ordered again.

Mo Zhong did as he was told, and suddenly the entire auditorium was plunged into darkness. Only Li Zexuan had a very thin beam of light, which looked particularly conspicuous.

Immediately afterwards, everyone heard Li Zexuan say: "I have a piece of paper in my hand now, and there are two very close slits on the paper. I will place the slits under the beam in a moment, and you will see what happens. !"

Students and teachers are all wondering: what can happen? Isn't it just one beam of light that becomes two beams of light?

However, the reality hit everyone in the face at one time, and I saw a section of light and dark stripes appearing on the white screen in the dark, and there were more than two bright stripes! But everyone clearly saw the paper that Li Zexuan held on it, and only divided two beams of light! Why are there so many streaks underneath?
