Answer:
- A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal A plane mirror makes an image of objects in front of it.
- Spherical mirror are those mirror whose reflecting surface is curved or those mirror obtained from a hallow glass sphere . there are of two types concave and convex mirror
- It is a type of spherical mirror in which reflecting surface is bulged inwards is called concave mirror.
- It is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light.
