Requests from our TA (and me) 1. You must show your work on numerical problems on homework to receive full credit. 2. You will receive no credit if you copy someone else’s homework or allow someone to copy yours. 3. Buy a stapler, and staple multiple homework pages together. If you don’t have the homework handed out last Friday, there are extra copies at the bottom of the homework return boxes. If you haven’t picked up you test #1 yet, it should be in the homework return box.

Three types of spectra Continuous spectra: hot dense objects (solids or dense gasses) emit light at all wavelengths, with hotter objects emitting more short wavelength light. Emission line spectrum: if a gas is hotter than whatever is behind it, bright lines will be seen in its spectrum. Absorption line spectra: if a gas lies between an object emitting a continuous spectrum and the observer, and if that gas is cooler than the object, it will absorb some of the light from the object, causing dark lines in the spectrum.
