A) \[\left[ \vec{E}={{E}_{0}}\hat{i},\,\,\vec{B}={{B}_{0}}\hat{j} \right]\]
B) \[\left[ \vec{E}={{E}_{0}}\hat{k},\,\,\vec{B}={{B}_{0}}\hat{i} \right]\]
C) \[\left[ \vec{E}={{E}_{0}}\hat{j},\,\,\vec{B}={{B}_{0}}\hat{i} \right]\]
D) \[\left[ \vec{E}={{E}_{0}}\hat{j},\,\,\vec{B}={{B}_{0}}\hat{k} \right]\]
Correct Answer: A
Solution :
E.M. wave always propagates in a direct perpendicular to both electric and magnetic fields. electric and magnetic fields should be along \[+\text{ }X\]- and \[+Y\]-directions respectively. Therefore, option is the correct option.
