What is the velocity of light in a diamond if the refractive index of diamond with respect to vacuum is 2.5?
Refractive index of the diamond (µ )= 2.5 We know The velocity of light in vacuum (c) = 3 × 108 m/s To find the velocity of light in diamond (v) Now, µd = c/v => 2.5 = (3 × 108)/v => v = ( 3 × 108 )/2.5 = 1.2 × 108 m/s
