Question

The refractive index of water is 1.33 and the speed of light in air
is 3 x 108m/s. calculate the speed of light in water.

Answer 1

Answer:

Refractive index may be defined as speed of light in air to the speed of light in water...

speed of light in air = 3×10^8 m/s

refractive index = 1.33

speed of light in water = 3×10^8/1.33 m/s

= 2.2 × 10^8 m/s
