Q6 of 36 Page 379

The velocity of light in water is times the velocity of light in vacuum. Find the refractive index of water.

Let velocity of light in vacuum=v

⇒ Velocity of light in water


Now,


Refractive index of a medium (water) =


⇒ Refractive index = =


Hence Refractive index of water = 1.33.
