Velocity of light in diamond, glass and ...

Velocity of light in diamond, glass and water decreases in the following order.

A

Water `gt` glass `gt` diamond

B

Diamond `gt` glass `gt` water

C

Diamond `gt` water `gt` glass

D

Water `gt` diamond `gt` glass

Text Solution

Verified by Experts

The correct Answer is:
A, D
The relation between the velocity of light in a medium and refractive index of the medium is
`v prop 1/n`
If the refractive index of diamond, glass and water are `n_D, n_g` and `n_w` respectively as `n_D gt n_g gt n_w` the velocity of light in these medium will be `v_w gt v_g gt v_D`.
