The refractive index of a medium of...

The refractive index of a medium of absolute permittivity ( ` epsi `) and absolute permeability ` (mu) ` with respect to vacuum is :

A

` sqrt((mu)/(mu_0 epsi _0)) `

B

` (mu_0 epsi _0)/(muepsi ) `

C

`sqrt((muepsi )/(mu_0 epsi _0)) `

D

`(1)/(sqrt(mu_0 epsi_0 ) ) `

Text Solution

Verified by Experts

The correct Answer is:
C
` mu = (C )/(v) and C = (1)/(sqrt(mu_0 epsi _0)) `
` gamma = (1)/(sqrt(muepsi)) `
` therefore mu= sqrt((muepsi )/( mu_0 epsi_0)) `
