Question

If the refractive index of glass is 3/2 and that of water is 4/3 respectively, find the
speed of light in glass and in water. (speed of light in air - 3 x 10 m/s)
010​

Answer 1

Explanation:

Explanation:velocity in a medium=speed of light in air/refractive index

vel in glass=2x10^8m/s

vel in water=2.25x10^8m/s
