An electromagnetic wave is propagating along the $+\mathrm{z}$-axis. Direction of electric and the magnetic field of this wave can be represented by

• Correct answer
  A

  $\overrightarrow{\mathrm{E}}={\mathrm{E}}_0\hat{\mathrm{i}},\overrightarrow{\mathrm{B}}={\mathrm{B}}_0\hat{\mathrm{j}}$
• B

  $\overrightarrow{\mathrm{E}}={\mathrm{E}}_0\hat{\mathrm{k}},\overrightarrow{\mathrm{B}}={\mathrm{B}}_0\hat{\mathrm{i}}$
• C

  $\overrightarrow{\mathrm{E}}={\mathrm{E}}_0\hat{\mathrm{j}},\overrightarrow{\mathrm{B}}={\mathrm{B}}_0\hat{\mathrm{i}}$
• D

  $\overrightarrow{\mathrm{E}}={\mathrm{E}}_0\hat{\mathrm{j}},\overrightarrow{\mathrm{B}}={\mathrm{B}}_0\hat{\mathrm{k}}$

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