This digital lab introduces the concept of how quantum mechanics and light relate with respect to the Hydrogen atom. The module revolves around the Hydrogen Atom Simulator, a Bohr model version of a idealized hydrogen atom as it interacts with photons of various wavelengths. Watch the electron jump to higher energy levels as it absorbs photons, then emit photon(s) and drop back to a lower level. Students can drag the electron between levels and shoot photons of different wavelength/frequency at the atom.
The module also includes an instructor's manual, student guide, worksheets, and background information requisite to understanding the concepts. The Thermal Distribution histogram gives a temperature dependent plot of occupied states for many, many atoms.
