Electromagnetic Waves Question 2
Question 2 - 24 January - Shift 2
The electric field and magnetic field components of an electromagnetic wave going through vacuum
is described by
$E_x=E_0 \sin (kz-\omega t)$
$B_y=B_0 \sin (kz-\omega t)$
Then the correct relation between $E_0$ and $B_0$ is given by
(1) $kE_0=\omega B_0$
(2) $E_0 B_0=\omega k$
(3) $\omega E_0=kB_0$
(4) $E_0=kB_0$
