Kundt’s method for measuring the speed of sound . In Fig. 17-51. a rod R is clamped at its center; a disk D at its end projects into a glass tube that has cork filings spread over its interior. Aplunger P is provided at the other end of the tube, and the tube is filled with a gas. The rod is made to oscillate longitudinally at frequency f to produce sound waves inside the gas, and the location of the plunger is adjusted until a standing sound wave pattern is set up inside the tube. Once the standing wave is set up, the motion of the gas molecules causes the cork filings to collect in a pattern of ridges at the displacement nodes. If f = 4.46 × 10 3 Hz and the separation between ridges is 9.20 cm, what is the speed of sound in the gas? Figure 17-51 Problem 107.
