DEMO OF DOUBLE SLIT INTERFERENCE (Mathematica Player format, 76 kB): Right click on link to save to your disk. This demo lets you control the direction in which the waves move, the wavelength and the distance between the slits. You can experiment to determine how changes in these variables affect the interference pattern. The demo was created in Mathematica 6 and runs under the free Mathematica Player, downloadable from the Wolfram Research website:

DEMO OF DOUBLE SLIT INTERFERENCE (Shockwave Flash format, 2MB):  Right click on link to save to your disk. This is a video file that you can "play" in Windows Media Player or RealPlayer. It simply shows how the interference pattern changes when the various variables are changed (direction in which the waves move, the wavelength or the distance between the slits). You can't control the changes in the variables, as you can when playing the demo in the Mathematica Player (above).

DEMO OF MUSICAL SCALES - TEMPERAMENT02.nbp (Mathematica Player format, 54 kB): Right click on link to save to your disk. This demo shows how the Pythagorean musical scale is constructed and allows you to change the ratio used in generating the scale. By reducing the ratio slightly, you can generate the ratios for the "meantone" temperament scale, which was used in Western music from the 1500s through 1800s. You can also generate the scale ratios for equal temperament (the standard in Western music since about 1900). The demo was created in Mathematica 6 and runs under the free Mathematica Player, downloadable from the Wolfram Research website:
