For an electromagnetic wave propagating through vacuum, $$\vec{k}$$, $$\vec{E}$$ and $$\omega$$ represent propagation vector, electric field and angular frequency, respectively. The magnetic field associated with this wave is represented by :

A

$$\dfrac{\vec{E} \times \vec{k}}{\omega}$$

B

$$\dfrac{\vec{k} \times \vec{E}}{\omega}$$

C

$$\omega(\vec{E} \times \vec{k})$$

D

$$\omega(\vec{k} \times \vec{E})$$
