The electric field and magnetic field components of an electromagnetic wave going through vacuum is described by

$E_{x} = E_{o} \sin (kz - ω t)$

$B_{y} = B_{o} \sin (kz - ω t)$

Then the correct relation between E $_{0}$ and B $_{0}$ is given by

Accepted Answer

E_{x}=E_{0} \sin (k z-\omega t)

B_{y}=B_{0} \sin (k z-\omega t)

\because

Velocity

=\frac{E_{0}}{B_{0}}

\frac{\omega}{k}=\frac{E_{0}}{B_{0}}

\omega B_{0}=k E_{0}
