A free electron is located in the field of a monochromatic light wave. The intensity of light is I = 150 W/m 2, its frequency is w = 3.4.1016 s –1. Find:
(a) The electron's oscillation amplitude and its velocity amplitude;
(b) The ratio Fm/Fe, where Fm and Fe are the amplitudes of forces with which the magnetic and electric components of the light wave field act on the electron; demonstrate that that ratio is equal to ½ v/c, where v is the electron's velocity amplitude and c is the velocity of light. The action of the magnetic field component can be disregarded in the equation of motion of the electron since the calculations show it to be negligible.
