If E and K represent electric field and propagation vectors of the EM waves in vacuum, ​

Question

If \(\vec E\) and \(\vec K\) represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by: (ω - angular frequency):

(1) \(\frac 1\omega(\vec K \times \vec E)\)

(2) \(\omega (\vec E \times \vec K)\)

(3) \(\omega (\vec K \times \vec E)\)

(4) \(\vec K \times \vec E\)

Answer 1

Correct option is (1) \(\frac 1\omega(\vec K \times \vec E)\)

Magnetic field vector will be in the direction of
