Question: A plane electromagnetic wave, with wavelength 3 . 2 m , travels in vacuum in the positive direction of an x axis. The electric field,
A plane electromagnetic wave, with wavelength m travels in vacuum in the positive direction of an axis. The electric field, of amplitude oscillates parallel to the 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 Parallel to which axis does the magnetic field oscillate? What is the timeaveraged rate of energy flow associated with this wave? The wave uniformly illuminates a surface of area If the surface totally absorbs the wave, what are the rate at which momentum is transferred to the surface and h the radiation pressure?
