Abstract

Our elementary texts discuss the nodal planes produced by two plane waves of the same amplitude and frequency travelling in opposite directions and leave us with the impression that the distance between nodal surfaces is usually one-half of the wave length. Yet this is far from the truth. Nodal surfaces having such a distance apart exist only for plane waves, the most common case being the standing waves in pipes. The purpose of this note is to call attention to a case wherein the distance from a nodal to a loop surface can be made very short, almost as short as you please, and thus to contribute to a greater clearness of understanding.
