# How Much You Know About Wave Optics? Trivia Quiz

19 Questions | Attempts: 1407  Settings  Wave optics is a division of optics that studies interference, diffraction, polarization, and other phenomena for which the approximation of geometric optics is not valid. This usage tends not to include quantum noise in optical communication, studied in the sub-branch of coherence theory. Confusing? This quiz might clear up your questions.
