Optics
Optics is the branch of physics that studies the behavior, propagation, and properties of light, as well as its interactions with matter.
Overview
Geometrical optics approximates light with rays to analyze reflection and refraction and design lenses, cameras, and telescopes. Wave optics explains interference, diffraction, and polarization, including their effects on image resolution. Quantum optics studies light and matter at the photon scale, connecting optical phenomena with lasers and quantum information.
Why it matters
Optical instruments enable diagnostic and therapeutic techniques in medicine, including endoscopy, optical coherence tomography, and laser surgery. In analytical sciences, spectroscopy applies light-matter interactions to characterize chemical composition and material structures.
