Serway & Jewett — Wave Motion: Problem 26

A sound wave propagates in air at \(27^{\circ}\text{C}\) with frequency \(4.00\text{ kHz}\). It passes through a region where the temperature gradually changes and then moves through air at \(0^{\circ}\text{C}\). Give numerical answers to the following questions to the extent possible and state your reasoning about what happens to the wave physically. (a) What happens to the speed of the wave? (b) What happens to its frequency? (c) What happens to its wavelength?
