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: ($$\omega$$ - angular frequency)

A

$$\frac{1}{\omega}\vec{K} \times \vec{E}$$

B

$$\omega\vec{E} \times \vec{K}$$

C

$$\omega\vec{K} \times \vec{E}$$

D

$$\vec{K} \times \vec{E}$$
