Re: [Phys-L] Hydrogen Spectrum Virtual Lab

I was afraid the photo would be blocked. Let me know if it works this time. The meter stick gives you the scale info you need.

Hi Bhopkisnsphysics,

I am writing off list.

That sounds excellent.  Hoping there is something in the photo to set the scale; perhaps the tube.  Could you send me the photo directly.  Images don't come through on phys-l.

Thank you so much!

  I took this photo years ago that shows the four visible emission lines of
hydrogen. The grating was 1.00 m from the tube and had 760 lines per mm.

  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
