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) https://www.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.
