Question

if the refractive index of a media is more then the speed will be more or less?

Answer 1

Answer:

Refractive index = n2/n1 = v1/v2

Hence more the refractive index less the speed .

eg. Refractive index of air = 1

speed of light in air = 3x10^8 m/s

Refractive index of water=1.33

speed of light in water = 2.25 x 10^8 m/s
