A plane electromagnetic wave is propagating along the direction 2 j ˆ i ˆ  , with its polarization along the direction k ˆ . The correct from of the magnetic field of the wave would be (here B 0 is an appropriate constant) :

1.             2 j ˆ i ˆ k t cos 2 j ˆ i ˆ B 0
2.             2 j ˆ i ˆ k t cos 2 j ˆ i ˆ B 0
3.             2 j ˆ i ˆ k t cos 2 j ˆ i ˆ B 0
4.            2 j ˆ i ˆ k t cos k ˆ B 0

Correct answer:             2 j ˆ i ˆ k t cos 2 j ˆ i ˆ B 0
