We envision these modalities on a spectrum. This spectrum can be rearranged depending ... We suggest integrating principles of Universal Design in all active learning modalities. LAMP faculty member ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

These 'Fraunhofer' lines are due to the absorption of light of specific frequencies by the gases in the upper atmosphere of the sun. \(1\). Line spectra are produced when electrons move from one ...
