This resource describes the physics of a simple infra-red detector. A simulation is used to illustrate energy level dependence and electron transitions in the detector. Discussion problems and comparison with other...
This resource, part of the Spectroscopy Lab Suite, illustrates the physics of a semiconductor Diode Laser. Students can create conduction and valence band energy levels and build in a bias due to impurity doping. The...
This activity asks students to analyze both the light curve from a pulsar in the crab nebula and the Fourier Transform of the light curve. From this students must find the period of the light intensity, determine the...
This site contains various applets and animations of physical processes, demonstrating various ideas in waves, optics, mechanics, and thermodynamics. The site also contains information on the theory behind diffraction...
