What percentage of the speed of light in vacuum is the speed of light in a diamond?

What percentage of the speed of light in vacuum is the speed of light in a diamond?|||Refractive index of diamond is 2.42.


Hence velocity of light in diamond = c/2.42


This as a % of velocity in vacuum


= (c/2.42) / c x 100


= 41.3
