The Imaging Principle of Mirrors, What is the Principle of Mirror Imaging?

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.

1. The plane mirror is upright and other large virtual images, which cannot be undertaken by the light screen.

2. The connection line between the image and the object is perpendicular to 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 the object are symmetrical with respect to the plane mirror.

5. The size of the image is equal, but the left and right sides are opposite.

6. The top and bottom of the image remain unchanged, and the left and right are interchanged.

The image in a plane mirror is formed by the intersection of the extension line of the reflected light and the extension line, 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. According to the characteristics of plane mirror imaging, the size of the image and the object are always equal.

The reflected rays are in the same plane as the incident rays and the signaling 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.

There are two methods of surface processing of glass to form a reflective imaging surface: electroless silver plating and vacuum evaporation, and the most commonly used is chemical silver plating. This method is to place silver nitrate.

Soluble in water, add ammonia and sodium hydroxide.

solution and dilute into silver hydroxide ammonia double salt to make silver plating solution. Invert sugar or formaldehyde, potassium sodium tartrate solution as the reducing solution.

The glass has been cut, edged (and polished if necessary), and the surface is washed before using stannous chloride.

The dilute solution is sensitized, then washed, and then mixed with silver plating solution and reducing solution to immediately dip the surface, and washed after the mirror is formed, and then copper plating and protective paint can be applied.

Mirror.

A mirror, or mirror in English, is an object with a smooth surface and the ability to reflect light. There are two types of plane mirrors and curved mirrors, plane mirrors are often used by people to sort out their appearance, curved mirrors are divided into concave mirrors and convex mirrors, which are mainly used as makeup mirrors, furniture accessories, building decoration parts, optical instrument parts and solar cookers, reflective telescopes and searchlights, reflecting telescopes, car rearview mirrors and so on.

In science, mirrors are also often used in telescopes, lasers, industrial equipment and other instruments, with regular reflective surface polished metal devices and metal-plated reflective film glass or metal products, often inlaid with metal, plastic or wooden frames.

Reflection: The reflection of light from a specular surface obeys the law of reflection, and its reflective ability depends on the angle of the incident light, the smoothness of the mirror surface, and the nature of the coated metal film. The imaginary line perpendicular to the mirror is called the normal, and the angle between the incoming ray and the normal and the angle between the reflection line and the normal are equal.

The object in front of the plane mirror is formed into an upright virtual image behind the mirror, and the distance between the image and the mirror is equal to the distance between the object and the mirror. If you want to see your entire length in the mirror, the mirror must be at least half the length of your body because the angle of incidence is equal to the angle of reflection. The reflective surface of a concave mirror is oriented towards the center of curvature.

The fundamental principle of mirror imaging is to obey the law of reflection of light.

The law of reflection of light: the reflected light is on the same plane as the incident ray and the normal, the reflected light and the incident ray are separated on both sides of the normal, and the reflection angle is equal to the incident angle, which can be summarized as three lines coplanar, two lines are separated, the two angles are equal, the light path is reversible, the light of the sun or the lamp shines on the human body, is reflected on the mirror surface, and the plane mirror reflects the light into the human eye, so you can see your virtual image in the plane mirror.

Mirror into the characteristics of guessing the spine image:

The object is an upright, equal-sized virtual image in a flat mirror. The omenous lines of the image and the object are perpendicular to the mirror. The distance from the image to the plane mirror is equal to the distance from the object to the plane mirror. The image and object are symmetrical with respect to the plane mirror. Virtual images cannot be undertaken with light screens. Like the size of the phase.

There are two methods of surface processing for glass to form a reflective imaging surface: electroless silver plating and vacuum evaporation, and the most commonly used is electroless silver plating. This method is to dissolve silver nitrate in water, add ammonia and sodium hydroxide solution and dilute it into silver hydroxide ammonia double salt to make silver plating solution. Invert sugar or formaldehyde, potassium sodium tartrate solution as the reducing solution.

After the glass is cut, edging (grinding and polishing if necessary), and the surface is washed, it is sensitized with a dilute solution of stannous chloride, then washed, and then mixed with silver plating solution and reducing solution to immediately immerse the surface, and the mirror surface is washed after it is formed, and then it can be plated with copper and coated with protective paint.
