Re: [Phys-L] Hydrogen Spectrum Virtual Lab

[Roger Key <rogerk@csufresno.edu>]

Hi Jeffrey,

I just started working on a similar lab .... nothing with UV or IR, but
there is this:

http://physics.bu.edu/~duffy/HTML5/emission_spectra.html

and one might be able to use a spectra such as this:

as an unknown ... ?  still seems too simple, but I am still working on it.

This will be for the virtual lab we will assign on 4/27.  I'm dedicating
most of my time right now to the other labs we're assigning before that.

I hope this helps :)
