Question

If `epsilon_0` and `mu_o` are, respectively, the electric permittivity and magnetic permeability of free space, `epsilon` and `mu` the corresponding quantities in a medium, the index of refraction of the medium in terms of the above parameters is….
A. `sqrt((in_(0)mu_(0))/(in mu))`
B. `sqrt((in mu)/(in_(0)mu_(0))`
C. `sqrt((in)/(mu_(0)in_(0))`
D. `sqrt((mu_(0)in_(0))/(in)`

Answer 1

Correct Answer - b
`mu=(c)/(v)=(1)/(sqrt(mu_(0)in_(0)))xxsqrt(mu in)/(1)=sqrt((mu in)/(mu_(0) in_(0)))`
