Document Summary
Announcements: provisional study guide posted, may be revised on friday once i see how far we get thursday, short mastering astronomy assignment posted late today, due tuesday, will catch up on email tomorrow morning. Exam prep schedule: clinic hours tonight (4:30-6:30, quick answers to study questions all day wednesday, help session friday held in room 208 from 9:30-11:30 and in the clinic from. 1:30-3:30: review on sunday: 8:30-11:30pm, extended clinic hours next monday: 2pm-6pm. Last time we saw that atoms can emit light of particular wavelengths/energies corresponding to their atomic transitions. This gives us emission spectra consisting of bright lines (from nmsu. Elements can also absorb wavelengths of these particular wavelengths as well. (remember that these atomic transitions can happen both ways) (molecules have these spectra too: their electron energy levels are more complicated. ) The hot core of the sun emits light of all wavelengths (learn why next class!)
