Question

The speed of light in diamond is 124000 km/s find refractive index of diamond if the speed of light in air is 300000 km/s

Answer 1

N=c/v
N=3*10 to the power of 8 /124000 to the power of 8
N=2.4193 is the refractive index of the given medium

Answer 2

Answer:

$refractive \: index \: of \: diamond = \frac{speed \: of \: light \: in \: air}{speed \: of \: light \: in \: diamond}$

$300000 \div 124000 = 2.42$
