Anonymous users2024-02-09The relationship between the plane mirror and the actual time is.
The two hours add up to 12 o'clock.
No matter what the time is.
It's all the same. This phenomenon illustrates.
The imaging principle of a plane mirror.
Moreover, the image of the object in a plane mirror is opposite to the object itself.

Anonymous users2024-02-08The sum of the actual time and the time in the mirror is 12
Because the line connecting 6 and 12 of the table is used as the axis of symmetry, the number of the corresponding positions on both sides of the axis of symmetry is added to 12, and this is also the case with the actual table and the table in the mirror.

Anonymous users2024-02-06The sum of the time indicated by the hand of the watch in the mirror and the actual hand is 12
For if the line "6" and "12" on the watch are taken as the axis of symmetry, then the sum of the numbers on both sides of the watch is 12, which is the same as the time indicated by the watch in the mirror and the actual watch pointer.

Anonymous users2024-02-05The applications of plane mirrors are as follows:1.Imaging with a flat mirror. For example, when making various mirrors, shopping malls and home decorations, the use of flat mirror imaging to enhance the effect of spacious and bright space in the interior.
2.The use of plane mirror can change the direction of light propagation, play a role in controlling the light path, such as making a periscope, when digging a well and digging a cave, use a plane mirror to reflect the sunlight to the operation area for lighting.
3.Plane mirrors reflect light to amplify small deformations for easy observation.

Anonymous users2024-02-04An object with a flat, smooth surface that can be imaged is called a plane mirror. The image formed by a plane mirror is formed by the reverse extension line of the reflected light from the object after being reflected by the plane mirror. Calm water, polished metal surfaces, glass panes, etc., are all equivalent to flat mirrors.
We call a mirror with a smooth plane of reflection a flat mirror.
Plane Mirror Imaging Features:
1. The plane mirror presents a virtual image of the same size as upright.
2. The distance between the image and the object and the mirror surface is equal.
3. The line between the image and the object is perpendicular to the mirror.
4. The image and the object are symmetrical with respect to the mirror face.
Application of Plane Mirrors1. Use plane mirror imaging.
2. Change the optical path.
3. Expand the field of vision.
Flat mirrors have a wide range of applications in life, such as: dressing mirrors for families, mirrors around the walls in the practice room, and small mirrors placed in the mouth when dentists check teeth. Submarines have plane mirrors in periscopes, microscopes, projectors, etc.

Anonymous users2024-02-03The principle of plane mirror imaging is as follows:
In the reflection of light, since 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), (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 the plane mirror is formed by the intersection of the extension line of the anti-grip light ray, so the image in the 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.
Imaging properties: However, in experiments, thin glass plates are often used instead of flat mirrors. Because the glass plate is used instead of a flat mirror, although the image is not as clear as that of the plane mirror, it is possible to observe the image of candle A and candle B at the same time, which cleverly solves the problem of determining the position and size of the image.
In order to see the image in the "mirror" more clearly, we require that the objects in front of the glass be as bright as possible, and the environment should be as dark as possible. The object behind the glass does not need to be lit, and the environment should be as dark as possible. Therefore, the plane mirror imaging experiment is suitable for conducting in a dark environment.
Plane mirrors can change the propagation route of light, but cannot change the beam properties, that is, when the incident light is a parallel beam, a divergent beam, and a converging beam, it is still a parallel beam, a divergent beam, and a converging beam after reflection.
Features: Equal size, isometric virtual image.
Test 1: Verify that the image formed by the plane mirror is the same size as the object >>>More
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
Friend, after reading the ** you sent, I can tell you that the effect of these pictures is not reached, and it is not enough to see only a small bright spot, but it is almost, you can still vaguely see that there are two small edges and corners next to the stars, which is a graphic halo, but it is impossible to distinguish that it is a ring, such a telescope can only be used for sightseeing, at most you can see the lunar crater, if your main purpose is astronomical observation, such a telescope you will regret when you buy it! Break a leg!
Do you mean to say: you (the eye) and the object are on opposite sides of the lens, but you see an inverted image of that object (whether magnified or zoomed out), like looking at a tree in the distance? >>>More
Macroscopically, according to the entropy increase theorem generalized by the second law of thermodynamics, entropy is irreversible, that is, the entropy of any object is increasing. When the mirror is broken, the entropy increases from an ordered state to a disordered state, which means that it can never be reduced in entropy, so the broken mirror cannot be reunited. >>>More
