weblinks (This page)

A set of notes in Word format containing all the content from the four webpages (above) on quantum behaviour is available here

Some Nice weblinks, some relevant and some useful

• Standing waves
  Shown well here http://www.walter-fendt.de/ph14e/stwaverefl.htm. This can get messy

  Nice violin one at (http://id.mind.net/~zona/mstm/physics/waves/standingWaves/standingWaves1/StandingWaves1.html)

• Interference of waves from two slits

  Explained very will with interaction
  http://www.colorado.edu/physics/2000/schroedinger/two-slit2.html
  Vary the slit separation to get a 'feel' for what is going on.
  
  
• Same sort of thing here
  http://www.walter-fendt.de/ph14e/doubleslit.htm
  And with this one you can change the wavelength whilst keeping everything the same.
  

• Diffraction of waves passing through narrow aperture

  Single slit diffraction at http://www.phys.hawaii.edu/~teb/optics/java/slitdiffr/
  And you can change the wavelength

• Diffraction by a grating Interactive applet to let you play with diffraction gratings.

• Evidence from electron diffraction that electrons show quantum behavior

  This is explained very well on the following interactive webpage
  http://www.colorado.edu/physics/2000/schroedinger/two-slit3.htm
  The content there is pitched just right, after that it can all start to get very complicated. The key idea is that electrons behave in exactly the same way as light in this experiment. They are diffracting and creating an interference pattern, just as light does.
