Optics & Light Calculators — Physics
Solve ray and wave optics problems with formula-backed tools. Snell’s law calculator finds refraction angles at a boundary, the lens maker’s equation derives focal length from curvature and index, and the Rayleigh criterion, optical resolution, and thin-film reflectance tools handle diffraction limits and interference coatings. Each shows the optical equation and inputs, useful for physics students and anyone designing lenses or imaging systems.
