  • question_answer 24)
        A plane electromagnetic wave propagating along x direction can have the following pairs of  and (a) Ex, B y                                              (b)E y, B z                      (c) B x, E y                                             (d)E z, B y             

    Answer:

      (b,d)As electric and magnetic field vectors  and  are  to each other as well as  to the direction of propagation of em wave, hence options (b) and (d) are correct.
