Explanation:
Concave mirror is used by dentist, solar furnace, reflector of a torch, etc.
Convex mirror is used in rear view mirrors.
An image formed by a plane mirror has the following characteristics: ... The size of the image is equal to the size of the object. Laterally inverted image (image of the left side visible on the right side). The distance of the image behind the mirror is the same as the distance of an object from the mirror.
The angle of reflection equals the angle of incidence.
Diamond shines because of total internal reflection of light.
Concave mirrors are not used as rare view because they will give an inverted image of the vehicles behind and for the driver it will be tough to assess the right position of the image coming from behind.
The image formed in the convex rear view mirror will be smaller than those formed in the plane rear view mirror.
