The velocity of electromagnetic radiation in a medium of permittivity

{\varepsilon _0}

and permeability

{\mu _0}

is given by

View answer and explanation

Correct option: C

\frac{1}{{\sqrt {{\mu _0}{ \in _0}} }}

Option C (

\frac{1}{{\sqrt {{\mu _0}{ \in _0}} }}

) is correct because the velocity of electromagnetic radiation is inversely proportional to the square root of the product of permittivity and permeability.
