why are spherical mirrors called so? name the two types of spherical Mirrors and draw their reflecting surfaces
Answers
Explanation:
This type of mirror has its surface of reflection curved outwards against the centre. It is also known as a diverging mirror because it causes rays to diverge upon reflection. Unlike images formed by concave mirrors, an image formed by a convex mirror are virtual in nature.
There are two types of spherical mirrors- concave mirror and convex mirror. Concave mirror- A spherical mirror whose reflecting surface faces towards the center of the sphere i.e., curved inwards is known as concave mirror.
Spherical mirrors are the part of glass sphere whose inner or outer side is polished and non-reflecting. Most of the curved mirror is a spherical mirror. If the reflecting surface of a spherical mirror is concave,it is called a concave mirror. If the reflecting surface is convex,then it is a convex mirror.
