Question

to trace the path of a ray of light passing through a rectangular glass slab for different angle of incidence and measure the angle of incidence angle of refraction and the angle of emergence.(with Observation table)

Answer 1

To trace the path of a ray of light passing through a rectangular glass slab for different angles of incidence. Measure the  ...

Answer 2

Answer:

1 ) .

Both angles are equal to each others i.e. ∠i = ∠e.

2 ) .

Angle of emergence also increases.

3 ) .

The light ray falls along the normal or the refractive index of the two optical media are  equal.
