Question

Refraction index of water with respect to air is 1.33 and that of diamond is 2.42.In which medium does the light move faster, water or diamond?​

Answer 1

Answer:

may be through water light move faster

Answer 2

Answer:

In water

Explanation:

$Refractive index = speed of light  in \: vacuum / speed of light in \: medium.$

Refractive index = speed of light in vacuum / speed of light in medium..

refractive index of diamond is more, hence the speed of light is lesser in diamond.

and

refractive index of water is less, hence the speed of light is move faster in water.
