Name the spherical mirror which has
(a) virtual principal focus.
(b) real principal focus.

Answered by admin @ 16/08/2021

Spherical mirrors which have :

Virtual Focus : Convex Mirror

Real Focus : Concave Mirror

Principle Focus:

It is a point on the Principle Axis such that paraxial light rays after reflection from the mirror pass through that point.

Virtual Principle Focus:

It refers to a principal focus located on the principal axis behind the mirror. Light rays meeting at the virtual principle focus shall produce a virtual image.

Real Principle Focus:

It refers to a principal focus located on the principal axis in front of the mirror. Light rays meeting at this point shall produce a real image.

Principle Focus is always defined for point object as source.
