These are series of short and sweet lab exercises that are more
qualitative - than quantitative - in nature. If you have other
suggestions - let me know.
Dioxide
Glass
PASCO makes a transparent cylinder of glass - they call dioxide glass
- and the following [purposely] bogus claim is made: "Dioxide
glass has an index of refraction that varies wildly with wavelength."
This is the reason, supposedly, for what you see below. The sheet of
paper has DIOXIDE GLASS printed twice - identically - with DIOXIDE in
blue and GLASS in red. Because the glass is so dispersive, red is
inverted but not blue. Shoot down this argument.

Polarization
of a Rainbow
Next time you see a rainbow determine whether the light from the
rainbow is polarized - and if so does the polarization change as you
sweep over the rainbow - and is so - how does it change?
