Answer 1

Answer:

• Convex mirror is used in rear view mirrors.

☞principles of concave mirror:

•A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light.

☞principles of convex mirror:

•Convex Mirror is a curved mirror where the reflective surface bulges out towards the light source. This bulging out surface reflect light outwards and are not used to focus light.

• Both the center of curvature and the focal point are located on the side of the mirror opposite the object.
