Those of you into surfing, music, rainbows, or even optometry will be totally stoked to learn about waves!

HELPFUL WEBSITES

• 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:
