Correct option is B

Correct option - B

The center of the reflecting surface of a spherical mirror is called the pole

A spherical mirror is a mirror that has a curved reflecting surface. It is part of a sphere and can be of two types:

  1. Concave Mirror: The reflecting surface is curved inward, like the inside of a spoon. It converges light rays that fall on it.

  2. Convex Mirror: The reflecting surface is curved outward, like the back of a spoon. It diverges light rays that fall on it.

Key Features of Spherical Mirrors:

  • The pole (P) is the center of the reflecting surface.
  • The center of curvature (C) is the center of the sphere from which the mirror is a part.
  • The focal point (F) is the point where light rays parallel to the mirror's axis converge (for concave) or appear to diverge from (for convex).

These mirrors are commonly used in applications like telescopes, headlights, magnifying glasses, and security mirrors.
