PDF - 221 KB Purpose The purpose of this activity is to use the 3 special rays to determine the images created by lenses. Introduction The purpose of ray tracing is to create a geometrical viewpoint of the creation of an optical image using the principles of ray (geometrical) optics. If done to scale, we can determine the properties of the image (size, position, real or virtual, etc.) created by different optical elements. While all rays from a given point on an object are focused by a lens to a unique point on the image, there are special rays whose properties are easy to remember and draw. For lenses, there are three special rays: a. A ray initially parallel to the axis refracts through the far focal point. b. A ray that enters the lens along a line through the near focal point emerges parallel to the axis. c. A ray through the center of the lens does not bend. Draw the object as an arrow with its base on the axis. Draw the three special rays from the…
