A . light ray bends as it enters glass and bends again as it leaves. . Light . passing through glass of a certain shape can form an image that appears larger, smaller, closer, or farther than the object being viewed. . A differentiated lab to test you skill with lab reports and geometric optics. Ray Tracing for Lenses. Lenses are used to focus light and form images. There are a variety of possible types; we will consider only the symmetric ones, the double concave and the double convex.. Q1: A double convex lens has radii of 5 cm and 20 cm a thickness of 2 cm and an index of 3/2. . Locate both H principal and focal points and compute the image distance for an object 16.4 cm in front of V1.
