Why sometimes the moon looks so big?

It's hard to say that the moon has a different feeling for China people since ancient times. The moon has always been in the hearts of China people, representing the sustenance of missing home. Just as I looked up, I found that it was moonlight and sank back, and I suddenly remembered my home in the famous "thinking about a quiet night". Telling Li Bai's longing for his hometown. Such a moon is the emotional sustenance of a wanderer; Especially in the Mid-Autumn Festival, we always have a feeling of "missing our relatives twice during the festive season". Many times, we look up at the bright moon to express our ideas. Whenever I admire the moon, is there an illusion that sometimes I suddenly feel that the moon is particularly big? Why is this?

At different angles, the length and distance of the light path through the atmosphere are different/the refraction angle is also different. Generally, at 6 or 7 o'clock in the morning and at 3 or 4 o'clock in the evening, the refraction angle will be larger and the sun will be larger. In fact, the main reason is your illusion. Ok, let's explain why sometimes the moon feels particularly big.

Why do you sometimes feel that the moon is particularly big?

Because when we look up at the moon, the angle formed by the position of eyes and head has a certain influence on the size of the moon. We feel the illusion that the moon is getting bigger because of the change of the rising angle of the moon, which leads to the change of the position of our head and eyes. Generally, when we look up at the moon, you will feel that the moon is getting bigger.

In fact, friends who have studied physics should know that our human eyes are equivalent to a convex lens. The working principle of convex lens must be clear to everyone. As the moon rises slowly. The moon will get closer and closer to us. When the paper bag is perpendicular to our position, the moon is closest to us. From rising to getting closer and closer to us, the virtual image becomes bigger and bigger as the distance between objects decreases. At this time, the object is an enlarged image.

Another most important reason is that when the moon rises slowly from the horizon, the space where the moon is located is relatively small. Compared with anything on earth, the moon at this time is big. When the second moon rises directly above our position, the appearance of the moon is insignificant compared with the vast universe. In fact, this reason is mainly because people are relatively different, so there is often the illusion that the moon is getting bigger.

Well, that's what I want to explain, why sometimes the moon feels so big. I hope my answer can help you.
