If electric and magnetic field strengths vary sinusoidally in time, being zero at t =0, then E =E0 sin 2πft and B= B0 sin 2πft. Let f =1.00 GHz here. (a) When are the field strengths first zero? (b) When do they reach their most negative value? (c) How much time is needed for them to complete one cycle?
