Ray optics is valid when
WebJan 10, 2016 · A ray is a simplified (asymptotic) description of a wave (which is a field) for the case when neither diffraction or scattering have to be considered. Ray optics requires that the curvature of wavefronts be large compared to the wavelength. JQK is correct that birefringent media require a slight modification of the simple ray algorithms for ...

WebRay optics, also known as geometrical optics, is the study of simple properties of light and optical instruments by assuming that light travels in a straight line. Ray optics deals with the geometry of the light. Light always travels in a straight line and the direction in which the light rays propagate is called the ray of light. WebRay tracing uses Maxwell's equation, which is valid as long as the light waves are waves that propagate around objects that are much larger than the light wavelength. Ray optics or geometrical optics do not define diffraction events, which require wave Optics theory. Other wave events such as interference can be modeled in moderate conditions ...
WebFresnel’s distance is the distance up to which the ray optics is valid in terms of rectilinear propagation of light. As there is bending of light in diffraction, the rectilinear propagation of light is violated. But, this bending is not significant till the diffracted ray crosses the central maximum at a distance z as shown
