Re: [Phys-L] Hydrogen Spectrum Virtual Lab

Thanks Dean,
Pending feedback from one of my Mac-user colleagues (and depending on how long I estimate it will take students to analyze the photo Barry sent me), I plan to incorporate the Spectroscopy Lab Suite into the lab. Kudos on some cool software.

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

You might find our spectroscopy programs helpful. Spectroscopy Lab Suite
covers creating energy level models in the the visible spectrum for a variety
of light emitting devices, Hydrogen Spectroscopy is just hydrogen but
includes IR and UV. Both programs are stand alone (no Java needed) and can
be downloaded from
Unfortunately, the on-line versions are no longer compatible with
contemporary browsers. But the downloadable versions run on both
Windows and Macs.
