Answer:
(i) During the propagadon
of electromagnetic wave along z-axis, let electric field vector be along .x-axis and
magnetic field vector be along y-axis,
i.e., and Refer Fig. 5(EP).5. Line
integral of over the closed
rectangular, path 1234 in x-z plane is
=
?(i)
(ii)
For evaluating over the surface
bounded by loop 1234, let us consider a rectangle 1234 be made of small strips.
One small strip of area ds = h dz. is shown in Fig. 5(EP).6.
Surface
bounded by strips 1234
?(ii)
(iii)
Give,
Putting
the values from (i) and (ii), we get
Or
(iv)
For evaluating , let us
consider a loop 1342 in y-z plane as shown in Fig. 5(EP).7.
?(iii)
To evaluate, let us
consider the rectangle 1342 to be made up of strips, each of area. Fig . 5 (EP) .8.
?(iv)
In the
relation,
is the
conduction current. The value of = 0 (in
vacuum).
Putting
values from (iii) and (iv), we get
or or
