WebRay optics: It is a geometrical optics. It is an optics in which light propagates in terms of rays. It considers light as a ray. It is discovered by Ibn al-Haytham. A figure to represent ray optics: Therefore, ray optics is valid when characteristic dimensions are much larger than the wavelength of light. Hence, the correct option is (C). WebTwo plane mirrors are inclined at 70o. A ray incident on one mirror at angle θ, after reflection falls on second mirror and is reflected from there parallel to first mirror. The value of θ : Q. How should a ray of light be incident on a mirror, in order that the reflected ray comes downwards? Which plane will contain these two rays and the ... WebSolution. Solution. A line is connected set of points that extends forever in both directions. A line segment is a part of line with two end points.
