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
= 41.3What percentage of the speed of light in vacuum is the speed of light in a diamond?
41.3%
because a diamond has an index of refraction of 2.419
