Diagram showing unpolarized light as intersecting waves approaching a circular polarizing filter. After passing through the filter, only light waves aligned with the filter's orientation emerge as polarized light, with reduced intensity.

$Diagram illustrating Brewster's law, showing a ray of incident, ordinary light striking a surface at angle p, with reflected polarized light at a 90-degree angle to refracted, partially polarized light. Arrows indicate light direction and polarization.$
