(d) A plane wave traveling along the x-axis in a polystyrene-filled region with
\epsi _(r)=2.54
has an electric field given by
E_(y)=E_(0)cos(\omega t-kx)
. The frequency is
2.4GHz
, and
E_(0)
=5.0(V)/(m)
. Find the following: (i) the amplitude and direction of the magnetic field
[C4, SP4] [1 marks]
(ii) the phase velocity [C4, SP4] [1 marks] (iii) the wavelength [C4, SP4] [1 marks] (iv) the phase shift between the positions
x1=0.1m
and
x2=0.15m
[C4,SP4][2 marks ]
