IF `E_(0)` and `mu_(0)` are respectively the electric permittivity and magnetic permeability of free space, `epsilon and mu` are the corresponding quantities In a medium, the index of refraction of the medium is

Options

A. `sqrt((muepsi)/(mu_(0)epsi_(0)))`
B. `(muepsi)/(mu_(0)epsi_(0))`
C. `sqrt((mu_(0)epsi_(0))/(muepsi))`
D. `sqrt((mumu_(0))/(epsiepsi_(0)))`

Answer

A

Explanation

Refractive index, `eta = (c)/(v) ((1)/(sqrt(mu_(0)epsi_(0))))/((1)/(sqrt(muepsi)))=sqrt((muepsi)/(mu_(0)epsi_(0)))`
