The velocity of light in diamond is 121000 km/s . The value of refractive index is (velocity of light in air ` = 3 xx10^(8) ` m/ s)

A

`1 . 26`

B

` 1 . 9`

C

`2 . 48`

D

`2 . 1 `

Text Solution

Verified by Experts

The correct Answer is:
C
Given, velocity of light in diamond
`v = 12100 km//s ` `= 121 xx 10^(6) m//s `
We know that,
Refractive index ` mu = (c)/( v)= ( 3 xx 10^(8))/( 121 xx 10 ^(6))`
`2 . 48`
