In an electromagnetic wave the electric field vector and magnetic field vector are given as $\overrightarrow E = {E_0}\widehat i$ and $\overrightarrow B = {B_0}\widehat k$ respectively. The direction of propagation of electromagnetic wave is along :
Solution
Direction of propagation = $$\overrightarrow E \times \overrightarrow B = \widehat i \times \widehat k = - \widehat j$$
