Re: [Phys-L] Hydrogen Spectrum Virtual Lab

Hi Jeffrey,

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

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 :)

Anybody got any ideas for a virtual hydrogen spectrum lab for an
algebra-based physics course for life science majors? They will have
studied two-slit interference and will have been introduced to the hydrogen
atom. I used to teach a lab where students took a picture of a hydrogen
lamp through a grating with a black and white instant polaroid camera. The
film was sensitive to visible and infrared radiation. The difficulty for
the students in analyzing the photo was establishing the angular scale;
that represents a geometry problem appropriate for the class. The
difficulty for me right now is, I didn't save any of the photos and I'm not
finding any on line. Still that's just one possible direction for the
lab. The PHET simulators relevant to that topic seem to be java programs
and I seem to recall there being a security issue with java. I don't
really want to ask the students to install a java runtime environment on
their computers and I'm not sure it is an option for all of t
