Ray Optics and Wave Optics (আলোকবিজ্ঞান)

 Unit - 6

Ray Optics & Wave Optics

আলোকবিজ্ঞান

Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances.

physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.
