For plane electromagnetic waves propagating in the z-direction, which one of the following combinations gives the correct possible direction for $\overrightarrow{E}$ and $\overrightarrow{B}$ field respectively?

• A

  $\left(\widehat{i}+\widehat{2j}\right)$ and $\left(2\widehat{i}-j\right)$
• Correct answer
  B

  $\left(-2\widehat{i}-3\widehat{j}\right)$ and $\left(3\widehat{i}-2\widehat{j}\right)$
• C

  $\left(2\widehat{i}+3\widehat{j}\right)$ and $\left(\widehat{i}+2\widehat{j}\right)$
• D

  $\left(3\widehat{i}+4\widehat{j}\right)$ and $\left(4\widehat{i}-3\widehat{j}\right)$

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