In a traveling electromagnetic wave, the electric field is represented mathematically asE = E0 sin[(2.0 × 1010 s-1)t - (5.3 × 101 m-1)x] where E0 is the maximum field strength.
(a) What is the frequency of the wave?
(b) This wave and the wave that results from its reflection can form a standing wave, in a way similar to that in which standing waves can arise on a string (see Section 17.5). What is the separation between adjacent nodes in the standing wave?
What is the terminal speed at which the bar falls? Imagine the bar remains horizontal and in contact with the rods at all times.
