Another simplifying assumption is that each medium through which the light travels (e.g., air, water, glass) is homogeneous and that all changes between media are abrupt at the interfaces. A consequence of these assumptions is that light travels… text/html 2026-04-27T10:47:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://physlab-wiki.com/phylabs/lab_courses/phys-120_130-wiki-home/spring-experiments/geometrical-optics/setup?rev=1777301274&do=diff Geometrical Optics ---------- Optical rail * 2 Optical rails * 4 post holders * 2 lens holders * Post holder (for screen or mirror) * Has 5-40 threading for screws * Light source * Screen * Red lens * Blue lens * Small mirror
