Check Your Understanding The equations for the wavelengths and the frequencies of the modes of a wave produced on a string: n=2nLn=1,2,3,4,5...andn=nv2L=nf1n=1,2,3,4,5... were derived by considering a wave on a string where there were symmetric boundary conditions of a node at each end. These modes resulted from two sinusoidal waves with identical characteristics except they were moving in opposite directions, confined to a region L with nodes required at both ends.Will the same equations work if there were symmetric boundary conditions with antinodes at each end? What would the normal modes look like for a medium that was free to oscillate on each end? Don’t worry for now if you cannot imagine such a medium, just consider two sinusoidal wave functions in a region of length L, with antinodes on each end.

In our model of sound we found (in a homework assignment) that the maximum molecular displacement sm, for sound in air, is much smaller than the distance between neighboring air molecules. From this fact we learn .. (circle the best answer) (a) ... that the validity of the model has broken down. (b) ... that sm describes the average position of very many molecules and is mean- ingful even when this is smaller than the microscopic scale of the material. (c) ... that apparently what matters is the tiny fraction of molecules that happen to be very close to others. (d) ... that some of what gets taught in 2214 is a gross oversimplification and falls apart under more careful scrutiny.
