Q. The oscillating electric and magnetic vectors of an electromagnetic wave are oriented along
A) The same direction but differ in phase by $90{^\circ}$
B) The same direction and are in phase
C) Mutually perpendicular directions and are in phase
D) Mutually perpendicular directions and differ in phase by $90{^\circ}$
Explanation
(c) $\overrightarrow{E}$ and $\overrightarrow{B}$ are mutually perpendicular to each other and are in phase i.$e$. they become zero and minimum at the same place and at the same time
