Question

R. I. of water is
4/3 and glass is 3/2.
If c = 3 x 10^8 m/s, then find the speed of light in glass and air. Hence find R. I. of glass with
respect to water​

Answer 1

Answer:

The absolute refractive indices of glass and water are

respectively. If the <br> speed of light is

, calucalate the speed of light in (i) vacuum, (ii) water.

The speed of light in a medium of refractive index is

, where speed of light in air.

Since the speed of light in glass is , the speed of light in air is

.

So the speed of light in water is
