In an electro magnetic wave, If $\vec B$ and $\vec E$ represents the magnetic field and electric field respectively. Then the direction of propagation of electromagnetic wave is along the direction of

$\vec E × \vec B$

The correct answer is Option (3) → $\vec E × \vec B$

In an electromagnetic wave, the direction of propagation is -

Direction of propagation = $\vec E × \vec B$ [Perpendicular to both $\vec E$ and $\vec B$]
