Why is the image in the mirror the opposite of reality?

Because they are symmetrical, the so-called mirror effect is such a principle.

Because they are all opposite, the images in the mirror are the opposite of reality.

Because the mirror is the one that causes the opposite of reality.

Because according to the principle of mirror imaging, it can be deduced, and the reflection of light is the same.

Because it was originally face-to-face to look in the mirror, it must be the other way around.

This is because the mirror is facing you, so it must be the opposite.

This is inherently face-to-face, so it's naturally the opposite.

Because it's a symmetrical figure, it's the exact opposite.

I think it's probably because people aren't perfecting their mirror-making skills.

The reason why this is the case is that the mirror is just an object.

Because they are all opposites, the image in the mirror is the opposite of reality. They are symmetrical, and the so-called mirror effect is one such principle.

The upper and lower z-axes are both positive, the left and right are the x-axis, the right is the positive direction, the front and rear are the y-axis, and the front is the positive direction. Since the mirror is perpendicular to the xy plane and parallel to the x-axis, in the mirror coordinate system, the positive direction of y is opposite to the true coordinate system, while the positive direction of the z-axis and x-axis does not change, so the person in the mirror is irreversible up and down.

There is no change in the x-direction of the person in the mirror, only the positive direction of the y-axis is reversed. To prove this, let's do an experiment. When you reach forward, the person in the mirror reaches out to you backwards and when you turn left, the person in the mirror also turns left.

But when we tap our left cheek with our left hand, the person in the mirror taps his right cheek with his right hand. In terms of movement, the person in the mirror cannot make the corresponding action with us, that is, if we raise our left hand, the person in the mirror will raise our right hand, why? To understand this question, we must first understand the principle of turning ourselves upside down in the mirror.

So, why do you understand that the person in the mirror is directly opposite you? That's because you think that the person in the mirror is in the same direction as yourself. Although this does not correspond to reality, the average human brain thinks so, in fact, the result of such a view is to make the person in the mirror rotate 180 degrees around the z-axis.

Then, the left hand of the person in the mirror naturally becomes your right hand, and students who have studied basic physics should be very aware of how the image in the mirror is produced. Just the illusion caused by the refraction of light on the mirror. The image we see in the mirror is a virtual image formed by the refraction of a real object on the mirror and the intersection along an extension line of refracted light.

At this point, the virtual image we see will naturally rotate symmetrically from side to side with the object.

So in reality, the front and back are upside down,The image you see in the mirror is naturally upside down, and when we do this action, it is naturally upside down because of the refraction of light.

It's the same. The self in the mirror happens to be the mirror image of oneself, the left and right are reversed. Raise your left hand in front of the mirror, but the self in the mirror is raising your right hand. And the self in ** is the self in the eyes of others.

Whether it is a flat or non-planar mirror (concave or convex mirror), the light is reflected by the mirror in accordance with the law of reflection, and the reflected light enters the eye to form vision in the retina. On a flat mirror, when a parallel beam of light touches the mirror, the whole will change direction in a parallel pattern, and the image is the same as what the eye sees.

The impact of light on a ** is super large, good light looks much whiter and more three-dimensional, and a good angle will also make people's faces look smaller and better.

This is normal, because when people look in the mirror, they can see themselves, and others only see the mirror, so they will see their own in the same way. Don't worry too much about this. As long as you don't think there's anything abnormal, it's fine.

If you are not worried, you can also go to a regular hospital for another examination. Hope it helps.

Whenever we look in the mirror, we find that our left and right sides are reversed, while the top and bottom remain the same, why is that? There are many different answers to this question, but the most plausible and simple explanation is that instead of being upside down, the mirror image is upside down, but upside down.

Since left and right are subjective judgments, let's simplify it a bit: imagine that you are facing north and have a mirror in front of you. If you jump, your reflection will also jump upside down, without being upside down.

If you go one meter to the east, your reflection will also move one meter to the east and not in the opposite direction. But if you go south, away from the mirror, your reflection will move north, i.e., in the opposite direction.

The mirror image is upside down.

The idea that mirrors are upside down, rather than upside down, is because when we look at our own mirror image, we automatically imagine ourselves in their position, i.e., left, right, front and back. This habit comes from the fact that we interact with people all our lives and interpret their left, right, forward, and backward in our own direction. When we see our own reflection, we instinctively identify him as another person, which is exactly the same except that all the features are in opposite directions.

For example, from a reflection perspective, the mole on the left side of your face is on his right.

But it's not the mirror that makes this shift, it's ourselves. We mentally turn ourselves upside down, thinking that we are in a position of reflection. We mentally invert our front and back, left and right, but the mirror actually only changes the front and back.

Imagine looking at yourself with a camera, i.e. facing your own footage, with left, right, front and back all reversed (if you look at yourself from the back of the camera, then nothing is reversed). If you move towards the screen (e.g. north), your recording will move in the opposite direction (e.g. south); If you move to the right (e.g. east), your recording will still move in the opposite direction (e.g. west).

Mirroring is not upside down.

The same applies to the text printed on the shirt. In one video, the forward, backward, and left and right directions are swapped, as if it were another person, so the text is still recognizable; But in the reflection, only the front and back are swapped, so it's like looking at transparent paper from the wrong direction, and the text is reversed.

To prove that the text on the shirt is not upside down in the mirror, you can shine a light on the text on the shirt so that it can be read from the inside. In other words, it's to look at the text from behind, but the right sleeve is still on your right and the left sleeve is still on your left. At this point, the text looks like it looks like it looks in the mirror:

The front and back are reversed, and the left and right are unchanged.

The appearance is the same, but the direction is not the same, because the self in the mirror is reversed, in mirror imaging, the left side seen is the left side of the person in reality, and the right side seen is the right side of the person in real life, but if two people face each other, the left side that one person sees is on the right side of the other person, and the right side that one sees is on the left side of the other person. This effect is also called mirroring.

The image in a plane mirror is made up of the intersection points of the extended lines of reflected light, so the image in a plane mirror is a virtual image. The virtual image is at the same distance from the object. The image is the same size as the object. According to the characteristics of a flat mirror, the image and the object are always the same size.

No matter how the distance between the object and the plane mirror varies, the image produced in the plane mirror is always the same size as the object. However, because people have a sense of "far, far, small" when looking at objects, their vision does seem to "get bigger and bigger" when they walk towards a flat mirror.

This is due to the size of the object as observed by the human eye, which is not only related to the actual size of the object, but also closely related to "perspective".

The self in the mirror is relatively close to the real appearance, but it is not exactly the same. In other words, it is not that he looks handsome in the mirror, but he is really handsome. When looking in the mirror, the mirror itself will play a certain role in decoration, and the picture in the mirror will look better.

Because the principle of the mirror is: the object image is symmetrical, with the mirror as the axis of symmetry.

It's as if your two hands, palms facing each other, left and right opposite, up and down the same.

Actually, the things in the mirror are not upside down. If you write the word "left" in the palm of your left hand and the word "right" in your right hand, and then open your arms and look in the mirror, you will find that the word "left" is still on the left, and the word "right" is still on the right, and it is not reversed. Of course, you will say, why is the word "left" on the right hand of the person in the mirror?

This is because the person in the mirror is face to face with you (I don't need to talk more about this truth, if the person in the mirror is facing away from you, hehe, wouldn't you be scared half to death), and the human body is symmetrical, so if you have to see the image of your left hand as the right hand of "that person", you will feel "left and right", but please understand that it is not that the image in the mirror is upside down, but because you use the left and right symmetry of the human body to "see" the image of your left hand as "that person" The right hand will come to the conclusion that the left and right sides are reversed. In fact, if people are not symmetrical left and right, but symmetrical up and down, (this is not difficult, you just have to lie down sideways and look in the mirror again), according to your opinion, now you in the mirror are upside down, but left and right are not upside down, isn't it?

This phenomenon is called "plane mirror imaging", and the characteristics of plane mirror imaging are generally as long as the plane mirror imaging is to use the law of light reflection. The light of the sun or lamp hits the person's body and is reflected on the mirror.

The image in a plane mirror is formed by the intersection of the extension lines of the reflected rays of light, so the image in a plane mirror is a virtual image. The virtual image is equal to the size of the object and the distance is equal. The image is equal in size to the object.

So the image and the object are symmetrical to the mirror. According to the characteristics of plane mirror imaging, the size of the image and the object are always equal. No matter how the distance of the object from the plane mirror changes, the size of the image it forms in the plane mirror always remains the same, and it is always the same size as the object.

Why are mirrors and cameras opposite? This is because they work on different principles.

Mirrors reflect the image by reflecting light, so they turn the image upside down. For example, when you are standing in front of a mirror with your left hand to the left and your right hand to the right of the mirror, the mirror shows an image of your right hand on the left and your left hand on the right side.

Cameras work by passing light through a lens and then projecting it onto a photoreceptor to capture an image. As a result, the camera does not flip the image, so your left and right positions in front of the camera lens are consistent with the left and right positions in the image captured by the camera.

In conclusion, mirrors and cameras work differently, so they display the image differently.

The difference between a mirror and a camera is their optical principle. Mirrors reflect light, while cameras refract light onto a photoreceptor.
