Part A.
Relation between electric field and magnetic field is given by:
In EM waves:
Electrostatic force due to electric field = Magnetic force
Fe = Fm
q*E0 = q*c*B0
E0 = c*B0
Where c = speed of light = 3.00*10^8 m/s
Part B.
Given that B0 = 8.5*10^-6 T
So,
E0 = 3.00*10^8*8.5*10^-6
E0 = 2550 V/m = 2.55*10^3 V/m
Part C.
frequency of EM wave will be:
Angular frequency = w = 2*pi*f
f = w/(2*pi)
Part D.
Relation between frequency and wavelength is given by:
wavelength, = c/f
= c/(w/(2*pi)) = 2*pi*c/w
Part E.
Given that: w = 3.5*10^7 rad/sec
So,
= 2*pi*3.00*10^8/(3.5*10^7) = 53.856 m
= 53.9 m = wavelength
