PHYSICS 002C Lecture 13 April 28, 2010 Serway and Jewett Chapter 26.1-2 – Images formed by mirrors Chap 26.1 Flat mirrors DEMO 1 The magic candle that burns under water! Geometric optics is the science of tracing rays through an optical system using the laws of reflection and refraction, the concept of refractive index, and the common notion that light rays travel in straight lines in a uniform medium. Ray tracing - The law of reflection ' 1 1 can be used to trace rays from a point source of light (the object) to see where a flat or curved mirror makes you think the object is, namely where its image is. The path of light through an optical system (consisting of lenses, mirrors, and apertures) Begins at an object from which rays of light emanate, Forms various real and virtual images, Is finally detected by eye or camera, or absorbed by a target. An image is an illusory copy of an object, such that the light rays coming from the image appear to be emitted from the copy [see footnote 2, p. 868]. Light rays from a point on an object are said to form a real image at a point where they cross each other. A virtual image of a point on an object is said to be located at a point in space from which rays projected back are apparently diverging. Note: A real image differs from an object because the latter has no
