An electromagnetic wave from a wire antenna travels (from the reader) toward the plane of he paper. At time t = 0.0 s it strikes the paper at normal incidence. At point O and time = 0.0 s, the magnetic field vector has its maximum value, 4.43 x 10 T, pointing in the negative y-direction. The frequency of this wave is 1.14 x 10 Hz. a) Find the associated electric field E at t = 0.0 s? (Remember you are finding a vector) b) Find the Poynting vector of the wave at time t 0.0 s? c) What is the magnetic field at point O at time t- 4.39 x 10-7s B (t=0)
