Reflection of Waves from Boundaries http://www.kettering.edu/~drussell/Demos/reflect/reflect.html This web site gives animations of the reflection of waves on a string. It includes the reflection of waves at hard boundaries, soft boundaries, and the reflection from an impedance discontinuity. These animations gave me a good visualization of how the wave behaves after encountering a boundary. This web site was extremely helpful for doing the homework assignment on waves. Wave Behavior Simulations http://www.hazelwood.k12.mo.us/~grichert/sciweb/wavebeh.htm I use this web site as a lab activity. By cutting and pasting the screen I make hand outs for my students. Then they have to fill out the sheet by following the web site. There are links to the following subjects: Moving waves, standing waves, circular waves, reflection of waves, refraction, reflection of circular waves, diffraction, Doppler effect, and super sonic shock waves. This lab gives students a visual reference to apply to class materials. Investigate the properties of light as it crosses from glass to air http://freespace.virgin.net/gareth.james/virtual/Optics/Refraction/refraction. html This is an applet that allows the user to move a source light of to see how the light bends when it moves from glass to air. The angle can be put at the critical angle and past it for total internal reflection. There is also a link to move an object in front of a converging lens to see where the image will form. This will be good to show students quickly what happens with refraction and lenses. Wave Motion Simulations
http://physics.ham.muohio.edu/p171s01/wave.htm This web site has applets that simulate wave motions. The superposition link has a nice visualization for two waves interfering with each other. It runs too fast when it is played, but I like the step buttons that allow you to step forward or backward in time so that you can see the interference at each step. I also like the reflection and refraction applets. These show the reflection and refraction of plane waves. All too often we deal with rays of...
