Spectroscopy Lab

Students set out to answer the questions: “How can atoms of different elements emit light of different colors or wavelengths”, and “How can the composition of a star be determined through spectroscopy?”  To work toward answering these questions, students first completed this Spectroscopy Lab in which they evaluated the effectiveness of using spectroscopy as a technique for identifying an unknown substance.   To do this, students observed the emission spectra of various isolated gases contained in discharge tubes, which is pictured below.
