When light propagates through a material medium of relative permittivity εr and relative permeability μr, the velocity of light, v is given by (c-velocity of light in vacuum)
- \(v=\sqrt{\frac{\epsilon_{r}}{\mu_{r}}}\)
- \(v=\frac{c}{\sqrt{\epsilon_{r} \mu_{r}}}\)
- v = c
- \(v=\sqrt{\frac{\mu_{r}}{\epsilon_{r}}}\)
Answer
(B) v= c _ r _ r
