Excerpt from On the Measurement of Virtual Height Some ambiguity in the measurement of the delay time of the pulse will always occur in a standard experiment. The reason for this ambiguity lies in the difficulty of prescribing a fixed point of reference on the pulse envelope so that the move ment of the wave group can be described as the movement of a single entity. The difficulty, of course, occurs because the pulse envelope must undergo a certain amount of distortion in its travel back and forth, including some spreading of its energy over a longer time interval than that which determined its inital width.
