Q. 1 D4.0( 3 Votes )

Through which of the following points, a ray passing through a centre of curvature and reflected by concave mirror will pass through?
A. Focus

B. Centre of curvature

C. Pole

D. All

Answer :

When ray of light passes through the centre of curvature of the concave mirror it strikes along the normal that means it is incident on mirror at 900.Hence the incident ray coincides with the normal and retraces its path i.e. passes through centre of curvature.

As other options don’t go by above fact, so they are incorrect.
