Question

Write laws of refraction. Explain the same with the help of
ray diagram, when a ray of light passes through a
rectangular glass slab.
​

Answer 1

Answer:

Explanation:

The two laws of refraction are:-

1.the normal , incident Ray and refrected Ray lie at same plane.

2.sini/sinr=constant

the ratio of sin of angle of incident with sin of angle of refraction is constant.
