Unformatted text preview: How does sound travel in air ? Sound is the transfer of energy in the form of waves. The waves travel by bumping air molecules together. The air molecules move back and forth, but the wave of energy moves outwards. The speed with which the waves travel through air depend solely on temperature . What are the natural frequencies of oscillation formed in a pipe that is open at both ends and a pipe open at one end and closed at the other ? f= v/2L where v is the speed of longitudinal wave in the rod . The longest wavelengths possible are : a) 2 L b) 4 L You find the frequency from the ratio . frequency = speed of sound/wavelength Added : L is the length of the pipe ....
