allows students of physics to do experiments on travelling longitudinal and transverse waves. TWave displays clearly how phase difference can give rise to a moving wave crest, and the meaning of amplitude, wavelength, period, and wave speed. A series of experiments are suggested, letting you change the amplitude and wavelength of the wave, using a ruler and a stopwatch as measurement tools.
In addition, you can enter your data into a table as well as print it.
The program can also be a useful resource for science teachers.
