The separation L between P and Q is 1.50 m, and the frequency f of the oscillator is fixed at 250 Hz. The amplitude of the motion at P is small enough for that point to be considered a node. A node also exists at Q . A standing wave appears when the mass of the hanging block is 300 g or 432 g, but not for any intermediate mass. a) What is the harmonic number of the standing wave pattern that appears when
