A loudspeaker emits a steady sound that travels through air at 340m/s.
(a) The distance between two consecutive compressions produced by the loudspeaker in air is 0.80m. Calculate the frequency of the sound.
(b) The same sound spreads into water where the speed of sound is 1500m/s while its frequency remains unchanged. Determine its wavelength in water.
(c) By what factor has the wavelength changed on moving from air to water? Show your working.
