Question

To trace the path of a ray of light, passing through a rectangular glass slab, for different angles of incidence. Measure the angle of incidence, angle of refraction, angle of emergence and interpret the results.

Answer 1

Answer:

angle of incidence = angle of emergence > angle of refraction

because the emergent ray and the extended incident ray are parallel to each other

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.
