Question

Light enters from air into the water which as a refractive index of 1.33. Calculate the speed of light in water if the speed of light in air is 3x10^8 m/s.

Answer 1

Answer:

It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s. Therefore, refractive index of the water can be measure by the Speed of light in water is 2.25 × 10^8 m/s.
