An incident ray makes an angle of 5° with the surface of a plane mirror. What will be the angle of reflection?

An incident ray makes an angle of ${75}^{\circ }$ with the surface of a plane mirror. What will be the angle of reflection?

The reflecting surface of two mirrors make an angle of 90° with each other. If a ray incident of one mirror has an angle of incidents of 30°, draw the ray reflected from the second mirror. What will be its angle of reflection?

An incident ray makes an angle of ${65}^{\circ }$ with the surface of a plane mirror. The angle of reflection in this case will be:

(a) ${65}^{\circ }$

(b) ${45}^{\circ }$

(c) ${25}^{\circ }$

(d) ${35}^{\circ }$
