A) \[[E={{E}_{0}}\hat{k},B={{B}_{0}}\hat{i}]\]
B) \[[E={{E}_{0}}\hat{j},B={{B}_{0}}\hat{j}]\]
C) \[[E={{E}_{0}}\hat{j},B={{B}_{0}}\hat{k}]\]
D) \[[E={{E}_{0}}\hat{i},B={{B}_{0}}\hat{j}]\]
Correct Answer: D
Solution :
\[\mu =E\times B\] \[={{E}_{0}}\hat{i}+{{B}_{0}}\hat{j}={{E}_{0}}{{B}_{0}}\hat{k}\] \[E\times B\]points in the direction of wave propagation.
