Question

A ray passing through the centre of curvature of a concave mirror is inclined at an angle ∝ to its principal axis. The angle of reflection for this ray equals

Answer 1

A ray passing through the centre of curvature of concave mirror is inclined at angle à to the p.

we known that laws of reflection of light .

I=r

then,Given angle of incidence=a°

then,following the laws

Angle of reflection =a°

Hope it helps!!
