Standing Waves on a Wave Demonstrator (with frequency) The relationship between frequency and wavelength for standing waves on a 0.90 m short-rod wave demonstrator is explored. The frequency is displayed at the bottom of the screen.
Waves Consisting of Single Pulses Characteristics of single pulse waves include direction of displacement and wave speed illustrated in the following slinky demonstrations.
Examining Quantum Oddities within the Context of Other Major Scientific TheoriesPablo A. Molina This article presents an epistemological discussion on the conceptual hurdles shared by quantum theory and evolution, gravity, and special relativity, and offers students a logical structure to deal with waveparticle duality, the uncertainty principle, boundary conditions, and the quantization of energy. Molina, Pablo A. J. Chem. Educ.2008, 85, 1229.

The Crucial Role of Kinetic Energy in Interpreting Ionization EnergiesFrank Rioux and Roger L. DeKock The experimental ratio of the ionization energies of H and He is 1.81. The authors show that it is not correct to interpret this ratio using a classical Coulombic potential energy model. Rather a quantum mechanical model is required in which both kinetic and potential energy play a role. Rioux, Frank; DeKock, Roger L. J. Chem. Educ.1998, 75, 537.
