Chapter 409: Refraction of Sunlight

In short, regardless of whether Mo Xiaoran understood what she was drawing, she had no intention of explaining this matter to Mo Xiaoran at this time.

But one thing, she has determined, is that the so-called "god" that appears on the big sand dune is simply a "mirage".

The phenomenon of mirage often appears in the desert.

If she hadn't seen this just now, she really wouldn't have thought about it.

The phenomenon of mirage is actually the refraction of sunlight when it encounters air of different densities.

At this time, just when the sun is setting, the probability of mirages appearing will be much greater.

In the desert, when the sand is baked by the sun during the day, the temperature on the surface of the sand layer will rise rapidly.

Due to the poor heat transfer performance of the air and when there is no wind in the desert, the vertical temperature difference over the desert is very significant.

The bottom is hot and the top is cold, the air density in the upper layer is high and the air density in the lower layer is low.

When sunlight passes from a high-density air layer into a low-density air layer, the speed of light changes.

Through the refraction of light, the phenomenon that occurs not far away is presented to others.

And the way that "fairy" appears is actually based on the principle of refraction of light.

At that time, the "god" they saw was not on the sand dunes at all.

Instead, he stood on a flat ground somewhere that was convenient for him to move, and that flat ground happened to be able to accurately reflect the characters onto the large sand dunes when the "mirage" phenomenon occurred.

People who are not aware of this phenomenon will regard it as a mysterious and magical scene.

Especially the ancients, it was easy to think of this aspect as a miracle.

Now, she can't tell anyone what's in her mind until she decides on that position.

This prevents the murderer from getting wind of the situation and causing the whole case to hit a dead end.

Mo Xiaoran knew that she must know something, but she didn't say it.

Although he was anxious, he knew that as long as Lin Ran was unwilling to talk, it would be useless no matter how hard he pressed her.

But the key problem is that he is afraid that Lin Ran will act alone because of what he discovered.
