Lab for 20 Nov 2007

Today we will use the known line emission spectrum from Mercury atoms to calibrate a diffraction grating, and then use our calibrated grating to determine the wavelengths of emission from hydrogen atoms.

So basically, we will measure the emission spectrum from hydrogen.

Procedure.

homework deadline extended

If you have not already seen, the homework that was supposed to be due this past Friday is now due tomorrow (Tues) at midnight.

I was getting a lot of questions, which indicated to me we didn't cover a couple of things well enough. We will go over some of the questions in class tomorrow, and hopefully by the end of it you will know how to do all of the problems ...
