For example, his sound-wave experiment moves a microphone along a tube to locate standing wave pressure minima and maxima. Comparing these positions with the tube boundaries helps distinguish pressure nodes from displacement nodes, turning an otherwise easy-to-confuse distinction into a direct measurement.[ref]Interesting and inexpensive experiments for high school physics by Joe Wolfe.
