The electric field in a radio wave traveling via vacuum consists of amplitude 2.5x10^-4 V/m and frequency 1.47 MHz.
i) Determine the amplitude and frequency of the magnetic field.
ii) The wave is traveling in the + x- direction. At x = 0 and t = 0, the electric field is around 1.5x10^-4 V/m in the - y-direction. Determine the magnitude and direction of the magnetic field at x = 0 and t = 0.
