Question

. Angle between incident ray and reflected ray is double that of the angle of incidence

Answer 1

Answer:

The angle of incidence is equal to the angle of reflection. If the incident ray falls along the normal to a surface, it will be reflected along the normal i.e., the right ray will retrace its path.

Answer 2

Explanation:

Angle of incidence is the angle between the incident ray and normal. Similarly refracted ray is the angle between the refracted ray and normal. ... Angle of incident = 70/2 = 35 degrees.
