Physics 261, General Physics III

Here are some links to websites that demonstrate concepts relevant to the course.

• Propagation with reflection and refraction  (using Huygens' Principle)

 
• Interference of two point sources, like a two-slit experiment.

 
• Normal Physics Lab, National Taiwan Normal University. Some very nice applets on waves, optics, relativity, and other things.

 
• Physics 2000 at U. Colorado Boulder. This site has on-line demonstrations and discussions of a number of topics in modern physics.

 
• Imaging atoms at the IBM-Almaden site. These images were made using scanning tunneling microscopy (STM).
   
• Quantum mechanics Applets.
   
• Special Relativity.
   
• Wave superposition.

 
• Fourier synthesis using audible sounds.

 
• Electromagnetic waves (applet).

 
• Physics World (from Hong Kong; select English in upper left corner).
