Lecture Notes Hydrogen Balmer Spectrum April 17, 2000
Check manual and Web for time limits on rectifying any grading problems. The last day of classes (May 1st) is the last date for resolution of all problems.
	The Spectrometer
Pre-aligned: make only adjustments that are essential. Ask for help if necessary. Don't disturb the alignment. Make sure slit and cross-hair are in sharp focus. Study the spectrometer with your partner to understand its operation.
Diffraction Grating Remember the equation: m = dsin	Understand the vernier scale. Practice reading it. Ask TA for help if necessary. Angles Total of 12 measurements - angles for 3 lines on the left and 3 on the right. - in 1st and in 2nd order.
One partner should measure the first-order lines (right and left) and the other should measure the second-order lines.
	No time extensions will be given and there will be no opportunity to perform any measurements or analysis once the laboratory period has ended.
