Cowabunga, dude. Those of you into surfing, music, and rainbows will be totally stoked to hit the waves!

from an official educational institution email address.
- Wave animations with nice explanations
- PhET Wave on a String (A frequency of 25 with no damping and a fixed end gives an approximate standing wave.)
- PhET sound wave interference
- PhEt Wave Interference: a more complex version of the previous sim
- Really nice animation of a standing transverse wave (Be sure to pause in order to see the superposition of crest-crest or trough-trough at the reflection points.)
- Another nice page with standing transverse wave animations (This site also ties in these concepts to music.)
- Video of standing longitudinal wave:
- Animation of a longitudinal standing wave (Run the Java aplet near the top of the page and select longitudinal from the drop-down menu.)
- Really nice animation of harmonics on a violin string
- Terrific overview of standing waves of all types
- Another animation incorporating transverse and longitudinal standing waves…Note that it shows longitudinal waves as if there are nodes at both ends of a pipe. This would be similar to being in a long hallway with all the doors closed. Try to put your mouse on the particles that aren’t vibrating (nodes.)
- World’s best Doppler effect video by Blaine Greenhalgh:
- The Doppler effect even has applications in Star Wars!
