If a ray of light is incident passing through the centre of curvature of a concave mirror, then the angle between the incident ray and the reflected ray will be equal to:​

Correct option is A

The correct answer is option (a) 0°

• As the ray of light passes through the center of curvature,it must be incident on the mirror surface along the perpendicular drawn on the mirror at the point where the ray is incident. And hence the angle of incidence is 0°.

Information Booster :-

•  In convex mirrors, rays do not actually pass through the center of curvature since it is virtual. However, the same principle applies to their extensions.
  
•  This concept is fundamental for studying image formation in concave and convex mirrors.
