Looking out the window on the high speed train, the trees in the distance look slow, and the trees i

Our eyes see things, the near and the far are not on the same plane, and our visual range is regarded as a sphere, so in the same range of viewing angles, the movement of near and far scenes is different.

For example, if two objects travel the same 30 degrees in your perspective at the same time, the distant scenery may move 50 meters, and the near scenery may only move 5 meters, at this time, their speed is the same, and in turn, the two scenery travel at the same speed, so it seems that the far one is slower and the closer one is faster.

Since you are sitting in a car and using the car as a reference, the speed of the things outside is the same, and what you see happens, because the distance is farther away from your eyes, so the image that forms on your retina is very small. At this time, your car is moving forward, and the angle changes due to the forward, and the larger the image formed at the same angle, the more sensitive the vision is, and the smaller the image formed, the slower it becomes.

In fact, the relative speed of the near and far trees is the same for the car, but because the near trees stay in our eyes for a short time, and the distant trees will stay for a longer time, so our eyes mistakenly think that the short time is fast, and the near trees move fast.

When you are in a car, the angular velocity of the tree you are close to is large, and the angular velocity of the tree near you is small, or the angle of view of the tree near you changes more than that of the tree near you, so you can see the movement of the tree near faster, and the movement of the tree in the distance is slower.

As a result of the different selection of references, the distant trees are moving forward relative to the nearby objects; Whereas, relative to objects that are farther away than distant trees, then distant trees are moving backwards. In short, it is forward with respect to a nearby object; It is backward with respect to distant objects.

This is the contrast of objects, the fast speed of the near object is because the high-speed rail is the object of contrast, and the slow speed of the far object is because the fast and backward object is used as an analogy, so it will produce a visual illusion.

It's a little perspective principle of the eye, you go to see a little perspective to see the mark tree and the point of the tree in the human eye; In reality, the first thing to make sure is that with the car as a reference system, both near and far scenery are moving backwards. Objects near and far are themselves stationary, and the speed of motion is the same.

Moving the same distance, because the perspective principle exists that the near scene causes the human eye to move farther, so it seems to move a larger distance. Therefore, in the eyes of the people on the train, it is the scenery near that moves backwards quickly, and the scenery that moves far away backwards slowly. When a person looks at a near and distant scene at the same time, he will unconsciously use the near scene as a reference frame, so that it seems that the distant scene is moving forward.

But in fact, after a while, you see, the distant scenery also falls behind the train. Sometimes, if you are far away to a certain limit, it is easy to have the illusion that the tree is stationary in the distance, so the position of the tree must be at the vanishing point of a point of perspective, and this vanishing point is static relative to you, which is also the basic principle of landscape painting. The most typical case is that you always feel that the sun and the moon are always moving with you because they are far enough away.

Finally, the reason why you can quickly get the distance between an object in space and yourself without calculating is because of the speed of movement of distant and near objects presented by the perspective principle, that is, the problem you asked is the way for the human brain to quickly judge the distance of objects.

The Doppler effect, where the frequency becomes faster when approaching and slower when moving away.

This is because the trees near are large and far small, and the speed at which the trees near them retreat expands, while those that are far away shrink.

Because when the distance is close, the approaching object will move at the same speed as itself, and it is actually moving on its own, and the tree is not.

Because the high-speed rail runs very fast, it will show the speed when it approaches the tree next to it.

Objects near and far are not on the same level in your field of vision, so their velocities are different.

Movement and stationary are relative, and the principle of taking a bus, the speed of the car is very fast, and the things around you are naturally very fast.

It's the Doppler effect, it's physical knowledge, and it's the same with listening to sounds.

This is a physical phenomenon called the Doppler effect.

You're also slow at afar, fast at close on the bike.

This is a problem of human vision, because there are more trees in the distance, so it looks slower, and there are fewer trees in the distance, so it looks faster.

You are in any car, the slow forward is fast.

That's the problem of relative speed, it's because you're close to you that you feel faster! For example, the moon revolves quite fast, and you can see that it feels very slow, just because it is far away from us!

How to say this, I can't necessarily say it clearly, I won't draw a drawing line here.

Our eyes see things, near and far are not on the same surface, our range of vision is seen as a sphere, then in the same range of perspective, the near scene and the far scene move in different states, for example, 2 scenes, the same period of time in your perspective walked the same 30 degrees, so far scenery may move 50 meters, near the scene only moved 5 meters, at this time, in your opinion, their speed is the same, in turn, the two scenery run at the same speed, It seems to you that the distance is slower, and the closer is faster. Since you're sitting in the car and using the car as a reference, the speed of the things outside is the same, and that's what you see.

The larger the rotation radius, the more you can't see clearly.

When looking at the trees, the reference is the car, so the trees on both sides go backwards! As for the house forward, I didn't study it! Hey hey, by the way, when you choose a tree as a reference, the house should be backwards!

In fact, the relative speed of the near and far trees is the same for the car, but because the near trees stay in our eyes for a short time, and the distant trees will stay for a longer time, so our eyes mistakenly think that the short time is fast, and the near trees move fast.

When you sit in a car, you have a large angular velocity relative to a tree near you, but a small angular velocity to a distant tree, or your perspective changes more than a tree near you, so you see a tree moving faster than a tree moving far away.

This is because what people think of as fast or slow comes from the speed of change in perspective. Trees in the near distance have a large velocity relative to the corners of the human eye, so the trees in the near distance move quickly. The same goes for at a distance.

That's the result of using the trees and poles on both sides of the railroad that goes backwards as references.

This junior high school physics has been taught, and it is the difference in reference. You sit in the car and you watch the tree go backwards, because you are sitting in the car and moving at the same time as the car, and you are using the car as a reference. If you're standing next to a tree, you'll see a car moving forward, and you're using the tree as a reference.

When you look at a tree in the near distance, you use yourself as a reference.

And looking at the trees in the distance is to use the road as a reference.

The problem of the reference object, the tree in front of the car is getting closer and closer to you or the car, and the tree behind the car is getting farther and farther away

This is due to the perspective of the angle, in fact, it seems that the distant trees are also retreating, but compared to the near ones, due to the influence of the angle, it seems that the near ones retreat faster than the distant ones.

The reference you choose is not the same.

The effect is different.

Mental movements, in fact, are just imagining them moving in your own mind.

This is because rest is relative and motion is absolute.

When we look at the scenery outside when we are taking the high-speed train, we seem to feel that the trees on the side of the road are moving, and this psychological phenomenon is not a phenomenon of movement.

When we see the scenery outside when we take the high-speed train, we seem to feel that the trees on the side of the road are moving, and this phenomenon is called relative motion.

Glad to have your question.

When you see a tree in a fast-moving car, you will see the shadow of the tree, and when you see another tree, the shadow of the tree is still there. When watching a number of Hong's movies, is it because the human retina has a short-term stay, so there will be movies?

1, because the eyes are not tracked and focused on this object Senbu (you can try to look at the same speed as the object in front of the stove, you can see this defense spike clearly (personally try to be effective, see the railing, the clarity is 60%+).

2. According to the theory of relativity, the length of the object is shortened in this case (the closer the speed of the vehicle is to the speed of light, the more noticeable). False
