Question

The light ray passing through the centre of curvature, after hitting the mirror will reflect at an angle of ______ with respect to the normal.

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

Answer 1

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

The ray of light passes through center of curvature of the mirror strikes the mirror along the normal. Hence gets reflected along the same path. Therefore, the angle of incidence is $0^{\circ }$. Hence, the angle of reflection = $0^{\circ }$ according to the law of reflection.
