Question

In the experiment of refractive
through a glass slab, the angle of
incidence should be less than
90 degree.
why?​

Answer 1

Answer:

90 degree will be less in the experiment

Answer 2

Explanation:

1)The angle of incidence is nearly equal to the angle of emergence.

2)The angle of refraction is less than angle of incidence.

3) Because light is traveling from rarer medium to denser optical medium.

4)The lateral displacement remains the same for different angles of incidence.
