Geometrical Optics Quiz

Geometrical Optics = A model of optics that describes light propagation in terms of rays Ray in Geometrical Optics = An abstraction useful for approximating the paths along which light propagates under certain circumstances Light Rays = Propagate in straight-line paths as they travel in a homogeneous medium Refractive Index = The property that causes light to follow curved paths in a medium

Diffraction = An optical effect not accounted for by geometrical optics Interference = An optical effect not accounted for by geometrical optics Absorption = A possible fate of light rays in geometrical optics Reflection = A possible fate of light rays in geometrical optics

Optical Aberrations = Geometrical aspects of imaging described by geometrical optics Homogeneous Medium = A medium where light rays propagate in straight-line paths Dissimilar Media = The interface where light rays bend or split in two Refractive Index Changes = Causes light to follow curved paths in a medium

<p>Wavelength = When small compared to the size of structures with which the light interacts, geometrical optics is an excellent approximation Light Rays = May be absorbed or reflected in geometrical optics Geometrical Optics = Does not account for diffraction and interference Optical Effects = Certain effects such as diffraction and interference are not accounted for by geometrical optics</p> Signup and view all the answers
