A plane electromagnetic sinusodial wave is traveling in the negative a direction. Its frequency is 10" cycles per second and the electric field oscillates in the 2 direction. The maximum electric field strength is Eo = 3 x 10-? [V/m]. a) What is the speed of the wave? b) What is the wavelength? c) What is the direction of the magnetic field oscillation? Draw the vector directions that you use to figure this out. d) What is the amplitude of the magnetic field oscillation? e) Write out the formulas for E and B
