HI TI folks,
One of my students has built the Light Mosaic snack which uses cellophane
tape to demonstrate the polarization effect. (Light passes through the tape
and different colors get different angles of polarization. The color
pattterns it produces are dramatic.)
I have two questions
1) I would like to re-create the snack without using cellophane tape. I
would like to be able to spray something from an aresol can that would
produce the same polarizing effect. This will allow a much finer mosaic of
colors. Does anybody have a suggestion of a spray that is clear and will
also polarize the light.
2) Is the polarization effect independent of the speed of light effect of
different colors through a prism. Are these two seperate phenomenon or
different sides of the same one? (Of course, I realize that Quantum
Electrodynamics will explain all of these effects but is there a more
classical explaination that connects these two effects.)
