✯ What is Convex Mirror ?

✒ A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. The image is smaller than the object, but gets larger as the object approaches the mirror.

The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc.

✯ What is Concave Mirror ?

✒ If the inner side of the spherical mirror is reflecting, it is called a concave mirror. Concave mirrors can form inverted and real images and also virtual and erect images.

The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc.
