For example, waves travel faster in deep water than in shallow. reflection: the property of a propagated wave being thrown back from a surface (such as a mirror) refraction: Changing of a light ray’s direction when it passes through variations in matter. The focal point is virtual because no real rays pass through it. refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. Thumbnail: Rays reflected by a convex spherical mirror: Incident rays of light parallel to the optical axis are reflected from a convex spherical mirror and seem to originate from a well-defined focal point at focal distance f on the opposite side of the mirror. Unlike concave mirrors, convex mirrors always produce images that have these characteristics: (1) located behind the convex mirror (2) a virtual image (3) an upright image (4) reduced in size (i.e., smaller than the object) The location of the object does not affect the characteristics of the image. 2.S: Geometric Optics and Image Formation (Summary).2.E: Geometric Optics and Image Formation (Exercises).2.A: Geometric Optics and Image Formation (Answers).Infinite images will be formed in multiple reflections, as each image is the result of another image. The overall magnification of a multiple-element system is the product of the linear magnifications of its individual elements times the angular magnification of the eyepiece. Regular Reflection can also be referred to as Specular Reflection and is simply understood by using a plane mirror. The same ray-tracing and thin-lens techniques developed in the previous sections apply to each lens element. The image formed by the first is the object for the second, and so on. These are analyzed by considering each element sequentially. 2.9: Microscopes and Telescopes Many optical devices contain more than a single lens or mirror. ![]()
