Consider two sound waves with wavelengths 5m and 6m. If these two waves propagate in a gas with velocity 330ms-1. Calculate the number of beats per second.
An oscillator vibrating at 1250 Hz produces a sound wave thattravels through an ideal gas at 325 m/s when the gas temperature is22.0°C. For a certain experiment, you need to have the same oscillatorproduce sound of wavelength 28.5 cm in this gas. What should the gastemperature be to achieve this wavelength?

This behavior suggests that the dominant excitations at low temperature are long-wavelength phonons. The only important difference between phonons in a liquid and phonons in a solid is that a liquid cannot transmit transversely polarized waves-sound waves must be longitudinaL The speed of sound in liquid 4He is 238 mis, and the density is 0.145 g/cm3 .
