Simply look at Kraus' graph in Figure 14-2. A sinusoid with
current amplitude equal to 1.0 at the center and current
amplitude equal to zero at the end is obviously a cosine
wave. Since the magnitude varies from 1.0 at the center to
zero at the end, taking the arc-cosine of the magnitude
yields the distance from the center in degrees.
Cecil,
Sorry, I missed the comments that Kraus made about the phase of a
standing wave. Is that the concept that is represented by the " ..." in
your quote above?
