Straight line of argument

One morning, the bird and the fish met next to a pillar.

It turned out that they were all looking at the pillar. The result is a wonderful thing. The pillars seen by the birds are straight, while the small fish sees the curves. The little fish saw this scene and said to the little bird, "This pillar is curved. The twisted rope looks like." The bird who heard this said quickly: "No, no. It is straight. It is like a straight line." Their opinions are different. So they kept arguing over who they were and who was wrong.

After a while, their mother saw that her child had not yet returned home, and hurried out to find the child. Their mother finally found the child. At first glance, it was still there to argue who was right and who was wrong. They may be because the argument is too fascinating. My mother is still not aware of her side. So Mom called him up. He only reacted. They saw their mother coming. I quickly told my mother about the whole thing. They originally thought that their mother would definitely agree with themselves. The result is what I expected. The two mothers laughed at the same time and laughed. Let's talk about the reasons. It turns out that this is due to the refraction of light. The refraction of this light is when the light is obliquely incident from one medium into another, and the direction of propagation is deflected. This phenomenon is called refraction of light. The criterion for judging the medium is the density of the object. Since the chopsticks are in the water, the light is emitted into the water from the air, and the density of the light and the water are different, so the refraction of the light occurs. It is precisely because of this that you will see two different answers.

Understand the reason in the middle, the quarrel also stopped.
