Question

Question 21.A ray is incident on a glass slab of refractive index √3 from air at an angle of 60° from
the surface. What is the angle of refraction? How much time will light take to come out of glass slab if
slab is 10 cm thick?​

Answer 1

Answer:

Explanation:

sin i/sin r=√3

√3/2sin r=√3

2sin r=1

sin r=1/2

r=45°
