This resource outlines experiments and explorations for students to understand the physics of infrared emission and detection. Simple tools are used. Questions meant to guide and engage students are included.
This resource discusses the energy levels of in a solid, including conduction, valence, and impurity bands. Transitions between levels that model phosphorescence are described. The importance of thermal transitions in...
This resource discusses the energy levels of a periodic solid, and the effects of impurities on the energy levels. Applications of the energy levels to light emission and color are explored. The site includes an...
This resource discusses the meaning of quantum wavefunctions in terms of measurement probabilities. The double-slit experiment is used to motivate the concept of probabilistic measurements. A shockwave applet is then...
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...
