If `epsilon_(0)` and `mu_(0) `represent the permittivity and permeability of vacuum and and `epsilon_` and `mu` represent the permittivity and permeability of medium,the refractive index of the medium is given by :-?

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
`mu = (c)/( v) = (1 // sqrt( mu_(0) c_1) )/( 1// sqrt ( mu c )) = sqrt((mu c )/( mu_(0) c_(0) )`
