Using Spectroscopy to Find Life on Other Planets

This lesson helps students understand how using both a wave model and particle model of electromagnetic radiation can be used to collect and interpret the transmission spectra of a planet’s atmosphere.  This activity should take approximately two 50-minute class periods and is designed to be used in an introductory high school physics class or a high school astronomy course.
