Why is the image in the mirror smaller than the object?

The combined opinions of the previous netizens are correct. If it is a convex mirror, the mirror will get an image that is smaller than the real thing. Or you are far away from the mirror, and the image in the mirror you look at seems to be small due to the perspective of the perspective, which is a sense of perspective, just like when you look at things in the distance, you will feel very small, which is caused by the perspective and perspective. See attached drawing.

You say flat mirror imaging.

The book says that the image of a flat mirror is as big as an object.

The experiment in the book also verifies this, and the candle that coincides with the candle in the mirror is as large as the candle in front of the mirror, indicating that the image in the mirror is the same size as the object in front of the mirror.

But when you look at an object in a flat mirror, the image of the object you see in the mirror is smaller than the object. This is because of the visual problems of the human eye. It is due to changes in the vision of the eyes that the image in the mirror is reduced.

This change of perspective has nothing to do with the plane mirror, for example, next to a very long and straight male luo, look at a car passing by, when you are close, the car is as big as a normal car, when the car is far away from you, you see the car will be smaller and smaller, this is not the car is getting smaller, but the perspective of your eyes is changing.

Got it?

There are several reasons why the image in the mirror is smaller than the object: 1. Because some mirrors are concave mirrors, some mirrors are convex mirrors, and the surface of the mirrors is uneven, so the size of the objects is different.

2. It is also related to the different postures and distances of people looking in the mirror.

3. When the plane mirror is at the same distance, the shadow should be the same. But because the background of the surrounding environment is different between the mirror and the mirror outside, your feeling is also different.

4. The effect of the mirror is different, because its lighting and viewing angle are different, so the effect of the reaction must be error.

5. The quality of the mirror is related, the effect of the mercury mirror and the flat mirror is different, which is better than the mercury one, and the price is higher.

Because, this is a convex mirror.

In the case of a flat mirror, the image in the mirror is as large as the object. If you have to say that the image in the mirror looks smaller than the object, you can only say that the object in the distance will look smaller.

According to the principle of plane mirror imaging, the distance between the image of the plane mirror and the original is twice that of the original to the mirror, there is a visual angle to analyze, the farther away the thing seems to be in your eyes, the smaller the image in your eyes, the human eye is like a convex lens imaging principle, the farther the thing in your eyes into the image of the smaller it is! So the farther away things are, the smaller they look!

The mirror surface is uneven and spherical. That is, a convex mirror or a haha mirror.

This is physics knowledge.

The near is large and far small, because the mirror is reflected by the curved line in the light letter, and it is far away from the slippery distance from Peitong, so it looks small.

Summary. There is little difference between the mirror and reality, kiss hello. Is there a big difference between the self in the mirror and the real appearance, the mirror is a flat reflector, and the mirror is a large distortion positive virtual image, which is basically a true reflection of the person.

**There is a difference between the appearance of oneself and reality, because the camera lens is a multi-curved lens composed of a lens to form an inverted real image, theoretically there is lens distortion, that is, deformation, and then after post-processing in the machine, it is normal for the picture to be different from the original appearance of the person. <>

<> the difference between the mirror and reality is small.

<> generally speaking, the perspective in the mirror is completely opposite to one's own perspective. In the same way, others generally observe directly through their eyes and what they observe is basically their own appearance, while in daily life, they can only observe their own face through a mirror. In this way, it is not difficult to find that the self in the mirror and the self in reality are opposed, but the positions are opposite.

In fact, in fact, the real self and the self in the mirror are actually almost the same, and the self in the mirror is also the real self, and the difference is not very big, just because the real self is a mirror image compared to the mirror. Because you are mirrored when you see yourself every day, you have long been accustomed to yourself in the mirror, and when you suddenly see yourself that is not mirrored, you feel different from usual. <>

<> the above is all of the "little difference between the mirror and reality", I hope it will help you<><

Summary. Moreover, due to the different genes, chewing habits, and face habits, the appearance of relatives is actually asymmetrical, which is why it looks good from some angles and is not good from some angles. After people are accustomed to seeing the "mirrored self", they will feel strange or unsightly when they look at the ** taken by others using the rear of their mobile phones.

And the front and back of the mobile phone or the lens of the camera have different focal lengths, so there will be some differences between the ** taken with the mobile phone or camera and the person.

Good afternoon, kiss, I'm a small degree, I'm glad to answer for you<>

There is a small difference between kissing in the mirror and reality. The appearance in the mirror can be said to be the closest to my original appearance, because the mirror is flat, and there is no focus length, staring at the beauty of the dead group or the influence of filters and other factors, but what you see from the mirror is the appearance of the mirror.

And the appearance of relatives is actually asymmetrical due to the different genetics, liquid and chewing habits and face habits, which is why it looks good from some angles and is not good from some angles. After people are accustomed to seeing the "mirrored self", they will feel strange or unsightly when they look at the ** taken by others using the rear of their mobile phones. And the front and back of the mobile phone or the lens of the camera have different focal lengths, so there will be some differences between the ** taken with the mobile phone or camera and the person.

The object in the mirror is virtual, but in reality, it is real, and the real distance between the object and the image in the mirror should be twice the distance between the object and the mirror. In short, the mirror file can present a real self, but it is still a little different from me, but the difference is not big. <>

The difference between yourself in the mirror and reality is still a bit big, the self in the mirror is not the real appearance, and the self reflected in the mirror is often better looking than the real self, because you are looking at yourself subconsciously and you will unconsciously see yourself better. When a person is looking in the mirror, about 30% of the image of the mirror is reduced to our own real appearance. In fact, the self in the mirror is symmetrical, for example, if you and your friend are standing in front of the mirror, you are on the left and she is on the right, but in the mirror, you are on the right and she is on the left.

This is hooked to the reflection of light in physics, in the mirror, the front and back are the same, the top and bottom are the same, and the size is the same, but the cavity of change is the symmetry of the left and right. In fact, in real life, the human face is slightly asymmetrical, and this asymmetry is difficult to see with the naked eye. However, because of the symmetry principle of mirror imaging, it is a good modification of the face shape, making the face look more beautiful and the nose more pretty.

It is better to look in the mirror at close rangeWhen you are closer to the mirror, you are also closer to the light source of the reflective light in the mirror, so the lighting effect is better, and the better it becomes, but in reality, when you meet with others, there is no gaffer to fill the light for you. And, look in the mirror up close.

The essence of plane mirror imaging is because of the observation results of the human eye, because the plane mirror is a virtual image, and if there is no observation of the human eye, it can be said that there is no image at all (of course, the observation of other animals is the same). When observing the reflected light, the human eye will mistakenly think that there is an object at the intersection of the reverse extension of the reflected light, and this object is a virtual image, because of human intelligence, people can distinguish between images and objects, while animals cannot distinguish between images and objects, just because their intelligence is insufficient. So you'll feel like you're looking at the hairstylist on the right.

In fact, looking in the mirror is just to make yourself better dressed. For things that suit us, such as hairstyles, we have to try them out to know which hairstyle is more suitable for us and can make us look more handsome. If you have time, you might as well change your hairstyle, maybe there will be unexpected gains, I wish you more and more handsome.

If you sit and look at it, you will feel that your legs are extremely thick, pure perspective problem, you need to know that everyone's perspective is the perspective you look at in the mirror, so don't care about your own thoughts, care about your own thoughts in front of the mirror. This is the same as "don't ask girls if I look good today, ask boys".

Oh, I think you're handsome on every side, so you don't have to mess around.

People have inner beauty and outer beauty, maybe you find yourself!

Yes, it means that you like change.

This is the principle of a plane mirror: the reflection of light.

Peculiarity. 1.The plane mirror is formed into a large virtual image such as upright.

2.The line connecting the image and the object is perpendicular to the width of the plane mirror.

3.The distance from the image to the plane mirror is equal to the distance from the object to the plane mirror.

4.The image and object are symmetrical with the plane mirror.

5.The mirror cannot be connected by the light screen to the bright light.

6.The size of the image is equal, and the left and right are reversed. Bi State 7The image formed by the plane mirror is an upright, equal-sized virtual image.

If you are far away from the mirror, the image we see with our eyes will be small, and this is because the image is far away from you. "The size of the image has nothing to do with the distance of the object" is based on experiments.

Just like when an object is very close to you, you feel that it is relatively large, and when it is far away, you feel that the object is smaller, and the size of the object itself does not change; (If you sit on the plane and look at the Qi Juye people on the ground like ants, it doesn't mean that the people have become the size of ants, this is mainly the relationship between the perspective and the relationship).
