Choose
the correct options from the following;
(a) The
associated magnetic field is given as
(b)
The electromagnetic field can be written in terms of the associated magnetic
field as
(c)
(d) 
Answer:
(a,b,c)Suppose an em
wave is travelling along negative 
-direction.
Its electric field is given by
which is perpendicular to z-axis. It acts along negative
y-direction.
The associated magnetic field
in
em wave is
As 
Thus, option (c) is correct.
The associated electric field can be written in terms of
magnetic field as 
.
Thus, option (b) is correct.
Angle between 
and 
is 90° and between and is 90°. Therefore 
90°=0 and 
90°= 0. Thus, option (c)
is correct
