View Resource Wave Packet Explorer

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 the composite wavefunction and all of the components, are shown in real space. Different results can be saved for comparison.

View Resource Wave Function Sketcher

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 heights. Students are then asked to plot the electron wavefunction in this potential by changing its nature, amplitude, wavelength, and phase in the three different potential regions....

View Resource Harmonic Phasors and Fourier Series

This resource from Johns Hopkins University has audio and interactive components. Various forms of the Fourier series description for periodic signals are based on alternate ways of writing a cosine signal. This resource goes over Phasors, Phasor Sums, Harmonic Phasor Sums, Gibbs Effect, Windowing, Fejer Window, and Hamming Window.

View Resource Full Wave Rectification

This website from Victoria Junior College contains an interactive simulation of full wave rectification. Slider bars allow the user to adjust capacitance and ohm levels. The simulation includes an animated graph.

View Resource Waves, Hollywood Movies, Circuits, and Matter: 4 Projects for the High School Physics Classroom

These projects were designed for use in high school physics classes and contain lessons on waves, circuits, matter and other basics. The various materials are available for download in individual files.
