Reflection: The primary interaction between light and a plane mirror is reflection. According to the law of reflection, the incident light ray (the incoming light), the reflected light ray (the light bounced off the mirror), and the normal (a line perpendicular to the mirror's surface at the point of incidence) all lie in the same plane. The angle of incidence (the angle between the incident light ray and the normal) is equal to the angle of reflection (the angle between the reflected light ray and the normal).

Image Formation: A plane mirror produces a virtual image of the object placed in front of it. The image appears to be located behind the mirror, at the same distance from the mirror as the object is in front of it. The image is laterally inverted, meaning it is a mirror image of the object (left becomes right, and right becomes left).

Reversal of Left and Right: As mentioned above, the image formed by a plane mirror is laterally inverted. This means that if you raise your right hand in front of a plane mirror, the image in the mirror will show your left hand raised. This reversal occurs because the light rays from your right hand are reflected to the left side of the mirror, and vice versa.

Conservation of Energy: The law of conservation of energy applies to the interaction of light with a plane mirror. The total amount of light energy incident on the mirror is equal to the total amount of light energy reflected by the mirror. This means that the mirror does not absorb or destroy any light; it simply redirects it.

No Change in Frequency/Wavelength: The frequency and wavelength of light do not change upon reflection from a plane mirror. This means that the color of the light remains the same after reflection.
