Question

The mirror with infinite radius of curvature is-
a) Convex mirror b) Concave mirror c) Plane mirror d) Impossible to get such mirror​

Answer 1

c) Plane mirror

Explanation:

As the radius of the sphere is infinite, so the radius of the curvature of the plane mirror is also infinite

Answer 2

Answer:

A plane mirror may be considered to be a part of an infinitely large spherical surface.

And, an infinitely large spherical surface will have infinite radius.

So, radius of curvature for a plane mirror will be infinite.
