Right Answer is: D

SOLUTION

CONCEPT:

  • A spherical mirror is a mirror whose reflecting surface is a part of a hollow sphere of glass.
  • One side of the mirror is well polished and reflecting, and another side of the mirror is opaque (often painted red).
  • Spherical mirrors are of two types - Convex mirror, and Concave mirror.
    • The image formed by the spherical mirrors depends on the position of the object.

EXPLANATION:

  • The diameter of the reflecting surface of a spherical mirror is called Aperture.
  • The point at which the light rays concentrate or appear to concentrate after reflecting from the spherical mirror is called the focus of the spherical mirror. It is represented by letter 'F'.
  • The center of the reflecting surface of a spherical mirror is called the Pole. The Pole lies on the surface of the mirror and is represented as 'P'.
  • Principle axis is not a fixed axis for a mirror. It can be any normal to the surface taken according to convenience such that the sign conventions become easier to observe.
  • The center of curvature is the center of the sphere and the reflecting surface forms the part of that sphere. It is denoted by the letter 'C'.
  • The radius of curvature is the radius of the sphere of which the reflecting surface of a spherical mirror forms a part, and is represented as 'R'.
