Many faculty now use the last few weeks of the quarter to go into stat mech, so they don't get to polarization at all. So currently it puts the TA's in a bit of a bind to have to qualitatively explain the following: text/html 2026-05-05T11:45:47+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-140-wiki-home/spring-experiments/polarization-lab/setup?rev=1777995947&do=diff PHYS143 Polarization Lab Setup Each station gets 3 plastic linear polarizers. One for each student to use at the beginning of the lab for a TA led exercise illustrating what they do. I typically use the ones from the old Photoelectric Effect lab that are found in room 112. text/html 2026-05-04T14:07:56+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-140-wiki-home/spring-experiments/polarization-lab/start?rev=1777918076&do=diff Polarization - PHYS143 (Updated April 2025) Introduction ---------- Waves In the discussion of wave propagation on stretched strings, it was pointed out that the vibration or displacement of the wave was transverse, i.e., perpendicular to the direction of wave travel.
