Question

Three light rays are passing from air to water. Each makes an angle of incidence 30 degree, 45 degree and 60 degree respectively. Find the angle of refraction in each case.

Answer 1

LAW-we know angle of incidence is always equal to angle of reflection.

So the answer of following case are -

1. In first case,

Angle of reflection=30 degree

2. In second case,

Angle of reflection=45 degree

3. In third case,

Angle of reflection=60 degree.

U can solve all the questions like this by understanding the law given above answers.
