Question
The magnetic field of a wave propagating through a certain nonmagnetic material in the positive y direction
has an amplitude of 30 mA/m and a frequency of-
10
Hz . If the wave is polarized on the positive z direction
and its wavelength is 12.6 meter, find the equation of the instantaneous Electric field. Assume the initial phase
is 0.
Select one:
O a. E(y, t) = -2.4īcos(10°t – y) V/m
12.6
O b. E(y, t) = 2400žcos(2710°t – 12.6y) V/m
O c. E(y, t) = 2.4ricos(10*t – y) V/m
12.6
O d. E(z, t) = 2.4jcos(10°t -
z) mv/m
12.6
O e. E(y, t) = 1.6žcos(t – 2.10®ry) v/m
O f. E(y, t) = 30žcos(10°t + y) mv/m
