Light with polarization parallel to the optical axis (need definiton) will experience an index of refraction $n_o$$n_e$$\Delta n = n_e - n_o$$\Delta$$t$$\lambda$$2\pi$$C$$\sigma_1 - sigma_2$ text/html 2024-06-21T11:43:50+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-120_130-wiki-home/archive/mechanical_resonance_notes?rev=1718984630&do=diff Simple Harmonic Motion and Mechanical Resonance (NOTES/IDEAS) Experiment Outline Day 1: * Have students build oscillators, with a focus on variety * Class discussion on commonalities between builds * Each group chooses a single system and measure the period text/html 2024-06-06T15:13:11+00:00 Anonymous (anonymous@undisclosed.example.com) http://physlab-wiki.com/phylabs/lab_courses/phys-120_130-wiki-home/archive/roleideas?rev=1717701191&do=diff Role ideas: * Record-keeper: * Types out info in the documents * Check that everyone is alright with what's written. * Hands-on: * Physically manipulates the apparatus to run experiments * Physics interpreter: * Observes/Analyzes the data as it comes in, may be responsible for doing quick sanity checks
