As an example, a standing wave can be constructed from two identical but counter-propagating traveling waves of the form ei(kx−ct) such that
In contrast to a standing wave, a traveling wave of the form ei(kx−ct) carries a constant flux.
This should come as no surprise, since a standing wave can be thought of as a resonance consisting of two counter-propagating traveling waves whose individual contributions to current flow exactly cancel each other out.
3.5.2 Current flow due to a traveling wave
Since momentum in the x-direction is px = mrx = kk, the current associated with the traveling wave may be written in the familiar form Jx = erx, where e is the particle charge and rx is its velocity.
