In an electromagnetic wave, the electric field vector and magnetic field vector are given as $\overrightarrow{E}=E_0\hat{\mathrm{i}}$ and $\overrightarrow{B}=B_0\hat{\mathrm{k}}$, respectively. The direction of
propagation of electromagnetic wave is along:

• A

  $\left(\hat{\mathrm{k}}\right)$
• B

  $\hat{\mathrm{J}}$
• C

  $(-\hat{\mathrm{k}})$
• Correct answer
  D

  $(-\hat{\mathrm{j}})$

Hence, the correct answer is option: 'D'.
