Question

A ray through the centre of curvature hitting the spherical mirror makes an angle ofwith the normal.

• A. $0^{\circ }$
• B. ${90}^{\circ }$
• C. ${180}^{\circ }$
• D. ${45}^{\circ }$

Answer 1

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

A ray of light passing through the centre of curvatureA 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.
