OK, I see what you are saying.
The voltage ALONG the line IS constantly changing. The signal is in the
form of a sinusoid. However, for a specific point on the line, the
voltage does not change, hence the name "Standing Wave." But as you move
your probe up and down the line, the voltage certainly changes; it has to
otherwise how would you have a peak or a null.
