An electromagnetic wave going through vacuum is described by $E=E_{\text{o}}\sin \left(kx-\omega t\right)$ and $B=B_{\text{o}}\sin \left(kx-\omega t\right)$ . Which of the following equations is true?

• A

  $E_{\text{o}}K=B_{\text{o}}\omega$

• B

  $E_{\text{o}}\omega =B_{\text{o}}K$

• C

  $E_{\text{o}}{B}_{\text{o}}=\omega K$

• D

  $E_{\text{o}}\omega K=B_{\text{o}}$
