Question

The plane of a mirror makes an angle ${30}^{\circ }$ with horizontal. If any vertical ray is incident on the mirror, then angle made by the reflected ray on plane mirror will be:-

• A. ${30}^{\circ }$
• B. ${45}^{\circ }$
• C. ${60}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

The correct option is C ${60}^{\circ }$

Plane mirror $H$:horizontal.

Vertical ray:$i$ Angle between mirror and reflected ray $={60}^0$.

Hence, Option $B$ is correct answer.
