Question

If the angle between the mirror and reflected ray is 230, what is the angle of incidence of the incident ray?

Answer 1

280 is the answer bro.

Answer 2

Answer:

Angle of incidence = 40°

Explanation:

In the question,

The angle between the Reflected ray and the Mirror is 230°.

So,

The angle made by the reflected ray with the Normal is given by,

90° - (230° - 180°) = 90° - 50° = 40°

Therefore,

As, according to the law of reflection,

Angle of incident ray with the normal = Angle of reflected ray with the normal

So,

Angle of incidence is given by,

Angle of incidence = Angle of reflection = 40°

Therefore, the Angle of incidence of the incident ray = 40°
