1. [1pt] Consider standing sound waves in a tube. Answer true (T) or false (F) to the following statements; e.g., enter FFF. The highest pressure and lowest pressure in the standing wave both occur where the particle displacement is the smallest. The frequency of the standing wave increases as the harmonic mode increases. For a pipe closed at one end, the pressure varies more at the closed end than at the open end.
