If epsi(0) and mu(0) are respectively, t...

If `epsi_(0)` and `mu_(0)` are respectively, the electric permittivity and the magnetic permeability of free space, `epsi` and `mu` the corresponding quantities in a medium, the refractive index of the medium is

A

`sqrt((mu epsilon)/(mu_(0) epsilon_(0)))`

B

`(mu epsilon)/(mu_(0) epsilon_(0))`

C

`sqrt((mu_(0) epsilon_(0))/(mu epsilon))`

D

`sqrt((mu mu_(0))/(epsilon epsilon_(0)))`

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `n = (c )/(v) = (1)/(sqrt(mu_(0) epsilon_(0))) . (sqrt(mu epsilon))/(1) = n = sqrt((mu epsilon)/(mu_(0) epsilon_(0)))`
