If electric and magnetic field strengths vary sinusoidally in time, being zero at t = 0, then
Question:
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.

(b) When do they reach their most negative value?
(c) How much time is needed for them to complete one cycle?
