Question

A ray through the Centre of Curvature hitting the spherical mirror makes an angle of with the normal.

• A. ${45}^{\circ }$
• B. ${90}^{\circ }$
• C. $0^{\circ }$

Answer 1

The correct option is C $0^{\circ }$

The ray through the Centre of Curvature is perpendicular to the tangent at the point of contact. Therefore, the angle which it makes with the normal is $0^{\circ }$ in this case.
