A plane electromagnetic wave, with wavelength 3.0 m, travels in vacuum in the positive direction of the x axis. The electric field, of amplitude 300 V/m, oscillates parallel to the y axis.
a. What are the frequency, angular frequency, and wave number of the wave?
b. What is the amplitude of the magnetic field component? Parallel to which axis does the magnetic field oscillate?
c. What is the time-averaged rate of energy flow in watts per square meter associated with this wave?
