1 class periods of 70 minutes each
Summary
Students will conduct a lab and be able to explain the difference between a line spectrum and a continuous spectrum in terms of how they appear through a diffraction grating. They will also
explain why different atoms emit different atomic line spectra and how this relates to the movement of electrons between energy levels in an atom.
