Question

In $\overrightarrow E $ and $\overrightarrow K $ represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by :

($\omega$ - angular frequency) :

${1 \over \omega }\left( {\overline K \times \overline E } \right)$

$\overline K \times \overline E $

$\omega \left( {\overline K \times \overline E } \right)$

$\omega \left( {\overline E \times \overline K } \right)$
