Boom
This program allows you to set up a standing wave in an air column and measure the wavelength and speed of the sound in the column. A tuning fork is struck above the mouth of a tube containing air and water. The water level is altered until the air column resonates and makes a loud booming sound. It is an example of forced vibrations producing resonance. The length of the air column is then one quarter of the wavelength of the sound. Measurements can be taken and the speed of sound calculated.
