Which of the following relation is correct?

View answer and explanation

Correct option: B

\sqrt {{\mu _0}{\varepsilon _0}} {E_0} = {B_0}

Option B (

\sqrt {{\mu _0}{\varepsilon _0}} {E_0} = {B_0}

) is correct because the speed of light,

c

, is related to the electric field amplitude,

E_0

, and magnetic field amplitude,

B_0

, by

c = E_0/B_0

and

c = 1/\sqrt{{\mu_0}{\varepsilon_0}}

.
