  • http://hyperphysics.phy-astr.gsu.edu/hbase/waves/standw.html#c1 CH 6/22
    • Standing waves definition
  • https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=10&cad=rja... CH 6/22
    • Doc download file. Lots of music string stuff. Good amounts of calculations as well. 
  • http://physics.bu.edu/~duffy/py105/Music.html CH 6/22
    • A bit conceptual. Specifically focused on musical instruments. A short bit on beats at the end.
  • http://web.stanford.edu/dept/astro/dorris/StandingWaves.pdf CH 6/22
    • Standing waves with strings, some interference. 
  • https://people.nscl.msu.edu/~iwasaki/PHY231/lecture/Ch11-1_Mar31.pdf CH 6/22
    • Contents makes it sound like it has a lot of stuff but it only covers standing waves and sound in tubes (open open, open closed etc.)
  • http://physics.appstate.edu/laboratory/quick-guides/waves-slinky CH 6/22
    • Standing waves, travelling waves, longitudinal waves, harmonics
  • http://labman.phys.utk.edu/phys135/modules/m10/waves.htm CH 6/22
    • Standing waves. Some short gifs and lots of pictures. 

 

-- Videos --

    • The video I've always wanted, a recording of the physical movement of guitar strings as standing waves! I put this at the top to make sure it was seen. Guy drops a camera into his acoustic guitar and plays a couple tabs and you can actually see the sinusoidal waves of each string as he plucks them. 
    • PhysicsEH on standing waves & nodes. Quick definition, ~3 mins.
    • Fairly thorough introduction to standing waves & nodes. ~10 mins.
    • Bozeman on standing waves & nodes. Introduction. Covers strings and tubes. 7 mins.
    • Doc Schuster on standing waves & nodes. Covers strings and tubes. ~10 mins.
    • Doc Schuster harmonics with tubes with 1 closed end. ~9 mins
    • Doc Schusters introduction to strings and tubes. ~10 mins.
    • ilectureonline introduction to strings and standing waves. ~7 mins
    • Example problem ilectureonline for strings and standing waves. ~4 mins.
    • Air waves levitating beats and small objects. Pretty incredible.

 

-- Simulations --

  • http://physics.bu.edu/~duffy/HTML5/wave.html CH 7/8
    • Standing wave sim. Very basic
  • http://physics.bu.edu/~duffy/HTML5/speed_of_sound.html CH 7/8
    • Fork tuner with frequency in a tube of water. Water level and frequency are adjustable.

    • Superposition of standing waves
  • http://physics.bu.edu/~duffy/HTML5/longitudinal_standing_wave.html CH 7/8
    • Longitudinal standing wave superposition (never thought I would see a sim on that...)
  • http://physics.bu.edu/~duffy/HTML5/reflections.html CH 7/8
    • Standing wave "reflections"
  • https://academo.org/demos/wave-interference-beat-frequency/ CH 7/8
    • Can turn sound on or off and hear beats and dissonance 1/2
