Features: Equal size, isometric virtual image.
Test 1: Verify that the image formed by the plane mirror is the same size as the object
Lay a large piece of paper on the tabletop, and set up a piece of glass on the paper to serve as a flat mirror. And note the position of the plane mirror. Place a lit candle in front of the flat mirror to see his image, and place another candle behind him to see if it coincides with him.
Conclusion: A flat mirror is the same size as an object.
Test 2: Experimental verification: the distance from the image of the plane mirror to the mirror surface is equal to the distance from the object to the mirror surface.
On the basis of the above experiment, write down the position of the two candles on the paper with a note, put them a few more times, then remove the candle and the glass, measure the distance between the candle and the image, and fill in the experimental results below
Number of experiments Distance from object to mirror Distance from image to mirror.
Conclusion: The distance from the image to the mirror surface of a plane mirror is equal to the distance from the object to the mirror.
Test 3: The image of the plane mirror is a virtual image.
On the basis of the previous times, the light screen is placed in the position of the candle image, and the image without candles on the light screen is observed, which shows that the image of the candle we see on the glass is not composed of light, and the plane mirror is a virtual image.
It turns out that the light is reflected by the plane mirror and enters our eyes, and we feel as if the light is coming out of the sky, but in fact it is formed by the reverse extension of the reflected light.

I really recommend that the landlord find a junior high school physics book to read. It's more detailed than anyone else.

The reflected rays are in the same plane as the incident rays and normals; The reflected and incident rays are located on either side of the normal; The angle of reflection is equal to the angle of incidence. It can be summarized as: "three lines are coplanar, two lines are separated, the two angles are equal, and the optical path is reversible", when the light is perpendicular to the incidence, the angle of incidence = reflection angle = 0°.
The light of the sun or lamp hits the human body and is reflected on the mirror surface (this is diffuse reflection), and the plane mirror reflects the light into the human eye, so that we see ourselves in the virtual image of ourselves in the plane mirror.

The principle of plane mirror imaging: the reflection of light, because there is no corresponding point (s) of the light source (s) behind the plane mirror, and the light entering the eye does not come from the corresponding point (s), so (s) is called a virtual image.
Looking in the mirror is such a principle. It can be said that as long as a flat mirror is used, it must be a mirror reflection. The image in the mirror is called plane mirror imagery, which is often abbreviated as a mirror image.
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.

Plane mirror imaging is a physical phenomenon.
Plane mirror imaging refers to the light of the sun or lamp shining on the person's body, which is reflected on the mirror surface and the plane mirror reflects the light into the human eye, so we see the virtual image of ourselves in the plane mirror. When you look in the mirror, you can see another "you" in the mirror, and the "person" in the mirror is your "image".
In mirror imaging, your left side is still on the left, and on your right you see is still on the right, but if two people are facing each other, your left side is on the other side's right, and your right side is on the other side's left beam. This effect is also called mirroring.

The principle of plane mirror imaging is to obey the law of reflection of light.
The Law of Reflection of Light:
The reflected rays and the incident rays, the permeable field lines are in the same plane, the reflected rays and the incident rays are located on both sides of the normal, and the reflection angle is equal to the incident angle.
Features of Plane Mirror Imaging:
1. The object is upright in the plane mirror, and the clumps shout the same large virtual image.
2. The connection between the image and the object is perpendicular to the 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 the object are symmetrical with respect to the plane mirror.
5. The virtual image cannot be undertaken by the light screen.
6. The size of the image is equal, the top and bottom are the same, and the left and right are opposite.

The principle of plane mirror imaging is to follow the law of reflection of light, and the reflected light is on the same plane as the incident ray and the normal; The reflected and incident rays are separated on either side of the normal, and the angle of reflection is equal to the angle of incidence. It can be summarized as three lines coplanar, two lines separated, two angles equal, and the optical path can be reversed.
Imaging in a flat mirror.
In the characteristic experiment, if the glass plate is not perpendicular to the tabletop, the image of the object will no longer be above the tabletop. The image formed by the object behind and the object in front cannot be at the same height. Therefore, no matter how you move an object, the image of the object and the object will not coincide, and therefore the image will not be able to compare the size of the object. >>>More
