Question

how is spherical mirror obtained ​

Answer 1

Answer:

spherical mirror obtained by cutting a transparent sphere and painted by silver outside or inside. these are of two types.

Answer 2

A spherical mirror is a reflecting surface which forms part of a hollow sphere.

How it obtains :-

Consider, a hollow glass sphere being cut by a plane. The section APB, cut by the plane, forms a part of a sphere and is known as a spherical surface. If either side of this spherical surface is silvered, we get a spherical mirror.

Types :-

Spherical mirrors are of two types :-

• Concave mirror :- A spherical mirror in which the outer bulged surface is silvered polished and the reflection of light takes place from the inner hollow surface is called concave mirror .

• Convex mirror :- A spherical mirror in which the inner hollow surface is silvered polished and the reflection of light takes place from the outer bulged surface is called convex mirror.
