The radius of curvature (R) of a spherical mirror is the distance from the pole to the center of curvature. It is represented by the letter R.

For a concave mirror, the center of curvature lies in front of it, while for a convex mirror, it lies behind the mirror.

The center of curvature of a spherical mirror is the center of the sphere of which the reflecting surface forms a part. It is represented by the letter C.

Understanding terms like “pole” is essential for precise communication and comprehension when discussing the properties and behavior of spherical mirrors. The pole is a specific point on the mirror’s surface, and its role is significant in various optical concepts related ...

In a concave mirror, the reflecting surface is curved inwards, while in a convex mirror, the reflecting surface is curved outwards.
