Abstract
"A new experiment appropriate for both general chemistry and physical chemistry students will be described. The experiment utilizes ""pocket size"" USB spectrometers (operating in the UV/vis region) coupled with fiber optic cables to record a solar spectrum. A further extension of the experiment involves recording spectra of a light bulb at several voltages (and thus resistances). Using provided software, students can fit black body distributions to their obtained spectra. The software will display the acquired spectrum, a simulation based on their guess temperature, a simulation based on their fit, and OMC$^{2}$ for both. Students can then compare their results to the known temperature of the sun and the known temperature vs resistance curve of tungsten."
