Real images, such as the one considered in the previous example, are formed by converging lenses whenever an object is farther from the lens than its focal length. This is true for movie projectors, cameras, and the eye. We shall refer to these ascase 1images. A case 1 image is formed...

The three types of images formed by mirrors (cases 1, 2, and 3) are exactly analogous to those formed by lenses, as summarized in the table at the end ofImage Formation by Lenses. It is easiest to concentrate on only three types of images—then remember that concave mirrors act like co...

This article reports the use of a computer-supported collaborative learning (CSCL) instruction designed to help students develop understanding of image formation by lenses. The study aims to investigate how students, working in dyads and mediated by multimedia CAL programs, construct shared knowledge an...
Microscope - Image Formation, Optics, Magnification: The objective collects a fan of rays from each object point and images the ray bundle at the front focal plane of the eyepiece. The conventional rules of ray tracing apply to the image formation. In th
The Image Formation Using Lenses lab uses an optical bench to determine the focal length of a converging lens and to investigate the relationship between the ob…

The idea of image formation using a new kind of metamaterials based on hierarchically organized mirror channels with semitransparent walls, metamirror structures (MMS) is analyzed. In case the MMS's have relatively small cell sizes from one to tens microns they are mechanically solid materials havin...
