Question

If the angle between the incident ray and the normal at the point of incidence is 45 degrees, then the angle between the normal and the reflected ray will be:

Answer 1

Explanation:

According to the first law of reflection of light, if the angle of incidence is 45 degree then the angle between reflected ray and the incident ray will be 90 degree.

Answer 2

Explanation:

When an incident ray strikes normally to any reflecting surface then the reflected ray will trace back the incident ray.

Hence angle between incident ray and reflected ray is 00.
