Question

A plane electromagnetic wave propagating along x direction can have the following pairs of E and B.

  1. Ex, By.
  2. Ey, Bz.
  3. Bx, Ey.
  4. Ex, By.

Options

  • b and c

  • a and c

  • b and d

  • c and d

MCQ

Solution

b and d

Explanation:

As the EM wave is plane polarized and its propagation is in +X direction. So direction of `vecE` and `vecB` will be in either Y and Z direction or Z and Y direction. 

Here in the question, electromagnetic wave is propagating along the x-direction. So, electro and magnetic field vectors should have either y-direction or 2-direction.
