Geometrical Optics Quiz

Geometrical optics is a model of optics that describes light propagation in terms of rays.

The simplifying assumptions of geometrical optics include that light rays propagate in straight-line paths, bend at the interface between two dissimilar media, follow curved paths in a medium with changing refractive index, and may be absorbed or reflected.

Geometrical optics does not account for certain optical effects such as diffraction and interference.
