Answer 1

Explanation:

40°

A Ray of light makes an angle of 50° with the surface is one on the glass slab. Then the incidence angle will be 40°.

Answer 2

Answer:

The angle of incident will be 50.

Explanation:

A Ray of light makes an angle of 50° with the surface is one on the glass slab.

Then the incidence angle will be 40°.

When the light ray strikes on the surface of the certain medium then the angle formed between incidence ray and the normal line is called incidence angle.

The incidence angle i = 40^{\circ}i=40

∘

Hence, The angle of incident will be 40°.
