A ray that is incident through the centre of curvature for concave mirror, is reflected back: Correct Answer Along the same path

CONCEPT:

Mirror

  • A mirror is a polished surface that reflects the light incident on it.
  • Types of the mirror:
    1. Plane mirror
    2. Spherical mirror
      • ​​Concave mirror
      • Convex mirror

Rays that incident on the spherical mirror:

  1. A ray incident parallel to the principal axis actually passes or appears to pass through the focus.
  2. A ray incident through the center of curvature is reflected back along the same path.
  3. A ray incident through the focus is reflected parallel to the principal axis.

  • We know that if a ray incident through the center of curvature then it is reflected back along the same path. Hence, option 2 is correct.
