A plane electromagnetic wave is propagating along the direction \(\frac{\hat{i}+\hat{j}}{\sqrt{2}}\), with its polarization along the direction \((\underline{Y}\). The correct form of the magnetic field of the wave would be (here B0 is an appropriate constant):
- \(E_{n} \frac{\hat{i}-\hat{j}}{\sqrt{2}} \cos \left(\omega t-k \frac{\hat{i}+\hat{j}}{\sqrt{2}}\right)\)
- \(E_{n} \frac{\hat{i}+\hat{j}}{\sqrt{2}} \cos \left(\omega t-k \frac{\hat{i}+\hat{j}}{\sqrt{2}}\right)\)
- \(B_{n} \hat{\cos }\left(\omega t-k \frac{\hat{i}+\hat{j}}{\sqrt{2}}\right)\)
- \(\mathrm{E}_{\mathrm{a}} \frac{\hat{i}-\hat{j}}{\sqrt{2}} \cos \left(\omega t+k \frac{\hat{i}+\hat{j}}{\sqrt{2}}\right)\)
Answer
(C) B_ n ( t-k i + j 2 )
