Provided by Living Graphs, Making Waves is a freely downloaded interactive physics package that helps students visualize and understand the motion and interference of transverse and longitudinal waves. Designed for senior high school and college physics students, the interactive program allows users to manipulate wave properties such as their amplitude, wavelength, phase shift, speed, frequency and damping; standing waves; and mks units. The site even provides online help and tutorials for teachers to help them integrate the software into curricula.
