Question

NEED HELP please.

Answer 1

Answer:

1. 23°

2. 65°

Explanation:

1.

The law of reflection provides that for the same medium, the angle of reflection equals the angle of incidence.

Similarly, here, angle of incidence and reflection will be 46°÷2=23°

2. Since the normal, angles of reflection and incidence lie on the same plane and also the angles of reflection and incidence are equal then the angle between the plane of the mirror and the reflected beam will be given by 90-25=65°
