2. (20 points) A plane electromagnetic wave, with wavelength 2.7 m, travels in vacuum in the positive direction of an x axis. The electric field, of amplitude 300 v/m, oscillates parallel to the y axis. What are the (a) frequency, (b) angular frequency, and (c) angular wave number of the wave? (d) What is the amplitude of the magnetic field component? (e) What is the intensity of the wave? The wave uniformly illuminates a surface of area 1.8 m2. If the surface totally absorbs the wave, what are (f) the radiation pressure? (e) the force on surface due to radiation pressure?
