Physics Question on Electric Field

For a medium with permittivity (e) and permeability (µ), the speed of light (v) is given by:

A

v=μ∈v=\sqrt{\frac{\mu}{\isin}}

B

v=μ∈v=\sqrt{\mu\isin}

C

v=1μ∈v=\frac{1}{\sqrt{\mu\isin}}

D

v=∈μv=\sqrt{\frac{∈}{μ}}

Answer

v=1μ∈v=\frac{1}{\sqrt{\mu\isin}}

Explanation

Solution

The correct option is (C): v=1μ∈v=\frac{1}{\sqrt{\mu\isin}}
