In a traveling electromagnetic wave, the electric field is represented mathematically as E = E0 sin[(1.7 × 1010 s-1)t - (6.5 × 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?
