Mirror reflection is the phenomenon in which light bounces off a smooth surface, such as a mirror, at the same angle at which it hits the surface. This results in an image appearing to be behind the mirror, with all the same characteristics as the object in front of the mirror.
Mirror reflection works due to the interaction between light and the smooth surface of the mirror. When light hits the mirror, it is absorbed and then re-emitted by the atoms in the mirror's surface. The angle at which the light is reflected is determined by the normal, or perpendicular line, to the surface of the mirror at the point of reflection.
The law of reflection states that the angle of incidence (the angle between the incoming light ray and the normal to the surface) is equal to the angle of reflection (the angle between the outgoing light ray and the normal). This applies to all smooth surfaces, not just mirrors.
No, a photon does not change when it is reflected off a mirror. The photon retains its properties, such as energy and frequency, when it is absorbed and then re-emitted by the mirror's surface. However, the direction of the photon's travel changes due to the law of reflection.
No, mirror reflection can only create a finite number of images. This is because each image is slightly smaller and dimmer than the previous one, and eventually, the light becomes too weak to produce a visible image. Additionally, the mirror itself limits the number of reflections as it has a finite size and can only reflect light at certain angles.
