Question

Find the speed of light in diamond whose absolute refractive index is 2.4

Answer 1

speed of light in diamond

=> speed of light in vacuum/ refractive index

=> 300000000 m/s / 2.4
=> 125000000 m/s
=> 1.25×10^8 m/s

please select it as the brainliest answer if it is helpful

Answer 2

Velocity of light in medium= Velocity of light in vacuum/ Refractive index of medium
-----------------
Refractive index of medium = 2.4
speed of the light in vaccum = 3 x $10 ^{8}$

= 3 x 10^8 / 3.4

1.25 x 10 ^8 m/s
