This resource illustrates the construction of scattering state wavefunctions in one dimension for a piece-wise constant potential. A barrier or well can be created from two potential steps, that can be of different...
This resource illustrates the construction of wave packet states from the superposition of plane waves. The user can add together different amplitudes of waves in either momentum or frequency space. The results, both...
This web page illustrates the motion of a quantum wavepacket, using 3D animations. Basic concepts and phenomena are shown using simulations rather than complex mathematics, although the functional forms of the states...
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 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...
