Chapter 707: The first class of Yanhuang Academy! (Thank you Gusheng_JUN...

phone-reading

"It's all right~! I won't say, I don't say, you two are innocent, right?"

Li Zexuan didn't bother to take care of Yan Shaoning. He thought that this guy

is really single by strength, what can he do?

"But when are you two going to get it? It will be dark in a while!"

But Li Zexuan looked at the sky and couldn't help saying.

"Uh……"

Mo Lingwei looked up, then threw the ice cubes in her hand to Yan Shaoning,

and muttered: "No more fun! No more fun! Let's talk about it tomorrow! It's

really strange that the situation yesterday cannot be replicated~! "

Suddenly received another ice cube, Yan Shaoning almost jumped up because of

the ice. This guy heard Mo Lingwei said that he would not play today, so he

quickly threw away the two ice cubes in his hand, and then rubbed the two

hardly about to freeze. Hands.

Li Zexuan couldn't help but curiously said: "What happened yesterday~? What

happened to you two yesterday~? I can tell you that, maybe I can give you some

help~!"

Mo Lingwei glanced at Li Zexuan suspiciously, and after thinking about it, he

said, "Zhang Chang, let me say it first. I invented this thing. You just help

me improve it. You are not allowed to take credit with me then~!"

Li Zexuan couldn't laugh or cry, "What credit can I take from you~? Hey, if

you don't want to say it, then forget it, I just have to go home to rest~!"

"Ehhhhhhh! Shanchang, don't leave! I said I said!"

Mo Lingwei looked anxious, the little girl rushed to Li Zexuan to block her

way, and then said:

"I... When I demonstrated ice cubes to make fire to Xiao Ningzi yesterday, I

accidentally discovered that when two convex ice cubes are separated by a

certain distance, they can see things in the distance through them, just like

the clairvoyance in the novel. , It's amazing~!

I hate that Xiao Ningzi accidentally broke the ice cube on the ground, and as

a result... As a result, we can no longer recover the magical phenomenon

before! We were doing this experiment just now~! "

The more Li Zexuan listened, the more surprised he became, because according

to Mo Lingwei's statement, the two of them probably accidentally built out the

telescope! He squeezed his chin, thought for a while and said:

"Miss Mo, the reason why you can't recover the previous magical phenomenon is

because the distance between the two ice cubes is wrong!"

Mo Lingwei retorted, "Impossible! The distance between the two convex ice

cubes yesterday is probably the same as the distance we placed today?"

Li Zexuan explained with a smile: "Even if your distance today is exactly the

same as yesterday, then there is no magical phenomenon like yesterday! In

fact, Miss Mo, you have overlooked one problem from beginning to end, and that

is the ice cube you used today. It’s probably not the same as the ice cubes

used yesterday!"

Mo Lingwei nodded, "Well, that's possible. After all, it's the first time I

made this thing by myself. How can I do it exactly the same every time? But

even if it's different, what's the impact? "

Li Zexuan smiled slightly and pointed to the ice mirror that had fallen into

pieces on the ground, and said, "Of course it has an effect! Miss Mo, you used

this ice cube to make fire yesterday. I wonder if you understand the

principle~?"

"I...I...Of course...I don't understand!"

Mo Lingwei opened her mouth and said with a little embarrassment: "This method

is what I saw in the handwriting of the ancestor of the Mo family. It said

that using this convex ice cube can turn sunlight into a small dot. That

little spot is very hot and can ignite something."

Li Zexuan suddenly knew from Mo Huai that Mo Zi was very knowledgeable about

geometric optics back then, and he was able to produce small hole imaging. In

contrast, using convex lenses to condense light seems to be a pediatrics.

Shaking his head, Li Zexuan said to Mo Lingwei and Yan Shaoning, who was

listening with gusto next to him:

"You two come down with me, I will tell you how the legendary clairvoyance was

made, and give you a task by the way~!"

After all, Li Zexuan turned around and went downstairs regardless of whether

they agreed.

After Mo Lingwei and Yan Shaoning heard these words, they were first taken

aback, and then surprised. The two looked at each other and hurriedly

followed.

"Hey! Xiaoxuan, you mean we can make clairvoyance?"

"Eh! Shanchang, wait for you!"

……………………

In a few moments, Li Zexuan came to the fourth floor, then walked through the

two-tower office area in the center of the building, entered the teaching

area, randomly found a classroom, pushed the door directly, and Mo Lingwei and

Yan Shaoning had already followed.

Seeing that Li Zexuan seemed to have the intention to give lectures, the two

found two seats in the first row. Mo Lingwei glanced privately at the neatly

arranged tables and stools and the tall podium in the classroom, and The

smooth blackboard felt very novel in her heart.

"Miss Mo, let me first tell you the principle of making fire from ice cubes!"

Li Zexuan first drew a convex lens on the blackboard, then looked at Mo

Lingwei, and said: "The shape and structure of this ice cube is

convex~www.mtlnovel.com~ Let’s call this structure a convex lens... ..."

One classroom, two students, one teacher, the first class of Yanhuang Academy

started quietly, but no one would have imagined that such a humble class

opened the curtain for the development of ancient Chinese optics. !

"Miss Mo, now you understand the principle of convex lens focusing~?"

Li Zexuan never expected that Mo Lingwei was such a questioning person. You

told her that convex lenses have a convergent effect on light. She asked why

you can converge. Okay, you can draw a light path diagram to explain to her

why convex lenses are. Being able to converge light, it will inevitably

involve the refractive index of different media. As a result, she asked what

is the refractive index and how these refractive indexes are

derived............

So this little piece of common knowledge of physics ended up talking about two

quarters of an hour. Thanks to the fact that Li Zexuan’s previous major

contained a lot of optical components, and his theoretical foundation is

fairly solid, otherwise, it’s really possible to be affected by this. The

little girl was upset!

However, it is gratifying that the two "students", Mo Lingwei and Yan

Shaoning, are very serious in attending classes.

"Well, I understand~! Shan Chang, you can tell us about the clairvoyance!"

Mo Lingwei twitched his chin and smiled at Li Zexuan.

Yan Shaoning also nodded and said: "Well, I also understand, Xiaoxuan, you can

go on!"

Although Li Zexuan in his previous life was an otaku, that doesn’t mean that

he has poor expression skills. On the contrary, in serious communication with

others, his expressive ability has always been very good and his thinking is

particularly clear. Perhaps it is because of this that Mo Lingwei and Yan

Shaoning could quickly follow his train of thought.

"Well, good! Now that you understand this, the next step is very simple~!"
