Abstract
Computer simulations for intermediate and advanced undergraduate courses provide students with tools that aid in visualizing difficult concepts. A suite of ten simulations has been developed for use in a sophomore/junior level course on vibrations and waves. This includes topics such as driven, damped oscillations; nonlinear oscillations of a pendulum; coupled oscillators; sound waves; and interference and diffraction. A feature of these simulations is the display of quantitative information about the phenomena in the simulation. For example, users can set the frequency and pressure amplitude of a plane sound wave, but the simulation also displays the particle velocity and displacement amplitudes and an animated graph of pressure, displacement and particle velocity of the wave. These simulations have been part of homework and discussion assignments in the related course.
