Question

A ray through the center of curvature hitting the spherical mirror, after reflection makes an angle of ____ with the normal.

• A. ${45}^{\circ }$
• B. ${270}^{\circ }$
• C. $0^{\circ }$
• D. ${90}^{\circ }$

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.
