Hello,

a student wanted to understand the following situation: when unpolarized light passes through a polarizer, 50% of the intensity passes through regardless of the orientation of the polarizer. I gave her two explanations. However, she felt that it would help to see a simulation on the situation.
Subsequently, I found the following YouTube presentation which was the student (and I as well) found helpful:

Being averse to vid. clips, I only ?skimmed? it. So did I miss a demonstration or is it only CGIs?

> From my distant past (ca. 1954), I remember the jump rope analogies.   I suppose one could design a shaker that shook the rope at random angles.  However, one may easily excite the rope w/ circular polarization, then select any angle of polarization w/ a slot.  Another slot would then show Malus? law.  e.g.

bc   thinks that demo is, unfortunately, CGI, also.


p.s. I prefer metal grates and X-band microwaves to demonstrate optics;  homologies, not simulations.
