6. A plane electromagnetic wave varies sinusoidally at 90 MHz and travels along the -z direction. The peak value of the electric field is 200 V/m and is directed along the +x directon. a. Find the wavelength, wave number, the period, and the maximum value of the magnetic field. b. Write expressions in SI units for the space and time variations of the electric and magnetic field. Include numerical values and include unit vectors to indicate coordinate directions for both fields. c. Find the intensity of the wave as it propagates through space. d. Find the average energy density in the radiation. e. What average radiation pressure would this wave exert upon a perfectly reflecting surface at normal incidence? f. What maximum acceleration would be imparted to a 50 g sheet with dimensions 1.00 m x 0.750 m
