Problem

A loudspeaker emits sound waves with a time period of

2.0\,\text{ms}

. (a) Calculate the frequency of the sound. (b) If the speed of sound in air is

340\,\text{m/s}

, determine the wavelength of these waves. (c) The loudspeaker is taken to a hill station where the speed of sound is

330\,\text{m/s}

. Without changing the frequency, find the new wavelength of the sound there.
