Question

The speed of an electromagnetic wave in a material medium of permeability. μ and permittivity ε is (A) (1/με) (B) (1/2με) (C) (1/√με) (D) (1/√2με)

Tardigrade Admin · Accepted Answer

If the absolute magnetic permeability of a medium is μ and its absolute electric permittivity is ε, the speed of electromagnetic wave in that medium, v=(1/√μ ε)

Q. The speed of an electromagnetic wave in a material medium of permeability. $μ$ and permittivity $ε$ is

$\frac{1}{μ ε}$

$\frac{1}{2 μ ε}$

$\frac{1}{μ ε}$

$\frac{1}{2 μ ε}$

$\frac{2}{μ ε}$

If the absolute magnetic permeability of a medium is $μ$ and its absolute electric permittivity is $ε$ , the speed of electromagnetic wave in that medium,
$v = \frac{1}{μ ε}$
