Question 215: EM waves

Question

The velocity of electromagnetic radiation in a medium of permittivity $$\varepsilon $$0 and permeability $$\mu $$0 is given by

Accepted Answer

The velocity of electromagnetic radiation in vacuum is = $${1 \over {\sqrt {{\mu _0}{\varepsilon _0}} }}$$

Answer

$${1 \over {\sqrt {{\mu _0}{\varepsilon _0}} }}$$

Answer

$$\sqrt {{{{\mu _0}} \over {{\varepsilon _0}}}} $$

Answer

$$\sqrt {{{{\varepsilon _0}} \over {{\mu _0}}}} $$

Answer

$$\sqrt {{\mu _0}{\varepsilon _0}} $$
