Electromagnetic Waves

For a plane electromagnetic wave propagating in the xx-direction, which one of the following combinations gives the correct possible directions for the electric field (E⃗\vec E) and magnetic field (B⃗\vec B) respectively?

  1. A.j^+k^, j^+k^\hat j + \hat k,\ \hat j + \hat k
  2. B.−j^+k^, −j^−k^-\hat j + \hat k,\ -\hat j - \hat k✓
  3. C.j^+k^, −j^−k^\hat j + \hat k,\ -\hat j - \hat k
  4. D.−j^+k^, −j^+k^-\hat j + \hat k,\ -\hat j + \hat k

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
