The index of refraction of diamond is 2....

The index of refraction of diamond is 2.0, velocity of light in diamond in cm/second is approximately

A

`6 xx 10^(10)`

B

`3 xx 10^(10)`

C

`2 xx 10^(10)`

D

`1.5 xx 10^(10)`

Text Solution

Verified by Experts

The correct Answer is:
D
`v_(d) = (C)/(n) = (3 xx 10^(8))/(2) = 1.5 xx 10^(8)` m/s
`therefore v_(d) = 1.5 xx 10^(10) ` cm/s
