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.
Introducing the Practical Aspects of Computational Chemistry to Undergraduate Chemistry StudentsJason K. Pearson Presents a laboratory exercise in which students use traditional second-year concepts such as the rigid rotor and harmonic oscillator approximations in conjunction with Gaussian 03 to reinforce practical aspects of computational chemistry. Pearson, Jason K. J. Chem. Educ.2007, 84, 1323.
Atomic SpectraWilliam F. Coleman In this Flash animation the user can view the atomic emission spectra (400-700nm) of eight different elements. A dragable marker allows the user to approximate the wavelength of the various spectral lines. The effect of resolution can be examined in the sodium spectrum in the region 550-600nm.

Bohr Hydrogen Atom Emission SeriesWilliam F. Coleman In this Excel spreadsheet students use interactive arrows to explore various series in the hydrogen spectrum. The arrows change the final quantum state of the series. A second tab opens a sheet that allows exploration of the spectra of other one-electron species, by varying the nuclear charge. The nuclear charge is entered and the arrows again control the final state of the spectral series.
