240. where a y denotes the unit vector is y direction. The wave is propagating with a phase velocity
243. A medium is divided into regions 1 and II about x = 0 plane, as shown in the figure 4.6 below. An electromagnetic wave with electric field E1 = 4? + 3 iy + 5 az is incident normally on the interface from region-I. The electric field E2 in region-II at the interface is
244. When a plane wave travelling in free-space is incident normally on a medium having Cr = 4.0, then fraction of power transmitted into the medium is given by
245. A plane wave of wavelength A, is travelling in a direction making an angle 300 with positive x-axis and 90? with positive y-axis. The E field of the plane wave can be represented as (E0 is a constant)j(cut
