Answer:
Explanation:
If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Image. Concave mirrors can form inverted and real images and also virtual and erect images.
uses of convex mirror:
Convex mirrors are used inside the buildings , They are also used in making lenses of sunglasses , They are used in magnifying glass , They are used in securities and they are used in telescopes
Uses of concave mirrors:
Concave mirrors are commonly used in torches, searchlights and headlights of vehicles to get powerful parallel beams of light.

Answer:
Concave mirror :- The mirror whose outer side is polished and inner or concave side is reflected ray.
Explanation:
Convex mirror :- The mirror whose inner side is polished and outer or convex is reflected ray.
convergence ray :- The rays of light which proceeding from the different points of a object tend toward the single point.
Divergence ray :- The ray which start from one point to different direction can be called divergence ray.
