"The nature of longitudinal waves is one of the most difficult topics encountered in physics courses for first examinations. The simulation on this disk allows the user to control important variables so that changes in the velocity and wavelength of a wave can readily be observed and discussed. Three waves can be displayed on the screen: the first two may be chosen to demonstrate either reflection interference, or beats; the third wave shows the sum of the other two waves. The pulses of compression and rarefaction are clearly visible in all waves. This dynamic model, which can be used for both classroom demonstration and individual learning, will greatly clarify the pupil's understanding and allow a step-by-step investigation of all the important concepts of wave motion."
