Expert Answer:

Given, Ey= 4 x103 Cos (3x108t -1.5 x) V/m
(i) frequency, v =?/2?
           ?        =3 x108 rad/sec
v    =3x108/2?
     =4.77x107 Hz
(ii)amplitude of magnetic field Bz = Ey/c
                                              =4x 103 /3 x 108
                                             1.33X 10-5T
