Q11 · Physics

When light propagates through a material medium of relative permittivity ϵr\epsilon_r and relative permeability μr\mu_r, the velocity of light, v is given by : (c - velocity of light in vacuum)

  1. 1v=cϵrμrv = \frac{c}{\sqrt{\epsilon_r \mu_r}}Official answer
  2. 2v=cv = c
  3. 3v=μrϵrv = \sqrt{\frac{\mu_r}{\epsilon_r}}
  4. 4v=ϵrμrv = \sqrt{\frac{\epsilon_r}{\mu_r}}
