An oscillator vibrating at 1250 hz produces a sound wave that travels through an ideal gas at 325 m/s when the gas temperature is 22.0c. for a certain experiment, you need to have the same oscillator produce sound of wavelength 28.5 cm in this gas. what should the gas temperature be to achieve this wavelength?
