Question

The speed of light in water is 2.25 108 m/s. If the speed of light in vacuum be 3 108 m/s, calculate the refractive index of water.

Answer 1

$\mathfrak{The\:Answer\:is}$

Refractive index = 2.25 108 m/s/3 108 m/s

= 0.125 * 108 m/s

$\boxed{Hope\:This\:Helps}$

Answer 2

Refractive index = 2.25 108 m/s/3 108 m/s

= 0.125 * 108 m/s
