Q. The oscillating electric and magnetic vectors of an electromagnetic wave are oriented along
AIIMS
AIIMS 2009
A
the same direction but have a phase difference of $90^{\circ}$
B
the same direction and are in same phase
C
mutually perpendicular directions and are in same phase
D
mutually perpendicular directions but has a phase difference of $90^{\circ}$
Solution:
In an electromagnetic wave, the oscillating electric and magnetic fields are mutually perpendicular and also perpendicular to the direction of wave propagation
$\frac{E}{B}=c$
ie, $E$ and $B$ are in same phase.
