If electric and magnetic field strengths vary sinusoidally in time, being zero at  t = 0,  then  E = E0 sin(2?ft)  and  B = B0 sin(2?ft).  Let  f = 4.50 GHz  here.     (a) After  t = 0, when are the field strengths first zero? (Give your answer in seconds.)  s     (b) After  t = 0, when do they first reach their most negative value? (Give your answer in seconds.)  s
