Reflection through Concave Mirror - Ray Optics - eSaral

Hey, do you want to learn about Reflection through Concave Mirror? If yes. Then keep reading.

Reflection through the concave mirror:


Reflection through Concave Mirror
F = Principal focus

P = Pole of mirror

C = Centre of curvature.

PC = Radius of curvature.

PF = Focal length.

When a narrow beam of light traveling parallel to the principal axis is incident on the reflecting surface of the concave mirror, the beam after reflection converges at a point on the principal axis.

Rules for ray diagrams:

  1. When a ray falls in the direction of the center of curvature of the mirror then it reflects back along the same path.
  2. A ray, parallel to the principal axis will after reflection, pass through the focus.
  3. A ray, passing through the focus is reflected parallel to the principal axis.
