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 ...

If the lens is removed the point where the rays meet will move 5\,cm 5cm closer to the lens. The focal length of the lens is. NEET - 2011. WebSep 26, 2016 · In the ray optics approximation,for light to be considered to be moving in a straight line path,we assume that the size of an obstacle must be very ... In ray-tracing we obtain approximate solutions to Maxwell's equations that are valid as long as the light waves propagate through and around objects whose dimensions are much greater ...
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. WebAnswer: C. Ray optics is valid when characteristic dimensions are much larger than the wavelength of light so that the rectilinear property of light can be used. Q2. According to Huygen’s Principle, the ether medium …
