For a plane electromagnetic wave propagating in x-direction, which one of the following combination gives the correct possible directions for electric field (E) and magnetic field
A
B
respectively?
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The wave propagates in the +x direction.
For an electromagnetic wave,
, and propagation direction are mutually perpendicular, and the direction of propagation is given by
Now the wave travels along +x, so:
Let's test the options
both parallel 
,
not perpendicular 
parallel (opposite direction) 
perpendicular components arranged such that
