A sinusoidal plane electromagnetic wave travels in a vacuum in the x-direction as shown in the graph. The period of the wave is T = 8.5 × 10-8 s. (a) The magnetic field reaches its maximum value, Bmax = 3.8 x 10-6 T, in the z-direction at some point and at some instant. Express the magnitude of the electric field at this position and time, Emax, in terms of Bmax. (b) Solve for the numerical value of Emax in V/m. (c) What is the direction of the electric field at this position and time?
