About

When a wave reaches the end of a medium, it doesn't just stop. But what does it do? In this simulation, you are certain to find out. View an incident, reflected, and transmitted pulse and observe how their speed, wavelength, and amplitude is dependent upon the density of the medium. It's like having a wave machine on your screen ... but you can take your time, repeat a trial, and easily investigate the answer to what happens when a wave reaches the emd of a medium.
