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.
An incomplete concept map is shown below, which set of terms for A, B, C and D would result in a correct map based on the concept of wave mechanics applied to a hydrogen atom?
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.

Guitar Strings as Standing Waves: A DemonstrationMichael Davis This demonstration uses an acoustic guitar to produce three unique harmonic vibrations, each of which is representative of a standing wave and illustrates the concept of quantization. Davis, Michael. J. Chem. Educ.2007, 84, 1287.

Flame Tests: Which Ion Causes the Color?Michael J. Sanger Students determine which of the ions in a series of ten commercially-available ionic compounds are responsible for the observed colors by performing flame test experiments using cotton swabs and a Bunsen burner. Sanger, Michael J. J. Chem. Educ.2004, 81, 1776A.
