The first site with information on mirrors is provided by BigChalk.com entitled Reflection (1). The site contains some informative descriptions, illustrations, and animations that teach the basics of reflection and the theory behind mirrors. There is a light reflection tutorial, an interactive mirror reflection pattern animation, a page on the basics of reflection, and other good information. The next site, Fun House Mirrors (2), is part of the larger Learner.org educational Web site. Visitors will learn and see how concave and convex mirrors affect images and the science behind this phenomenon. The third site, provided by the University of Illinois Physics Department, continues the theme by providing a long list of questions and answers related to mirrors. Called Lenses and Mirrors (3), the site offers information on topics such as Uses of Mirrors, Mirror Basics, What a Mirror Does to Faces, Mirrors Big and Small, and much more. The University of Buffalo Department of Physics maintains the next site called Mirrors and Lenses and Their Uses (4). Over fifty pages are available that delve deeper into the science behind mirrors and provide many informative graphics that should help non-experts better understand the concepts. The Light and Optics Lessons (5) page, which is part of the Ithaca City School District's Science Zone site, is the fifth in its series. Of the various activities offered, the Reflection of a Convex and Concave Mirror lessons offer interesting animations and brief and informative descriptions, while others let users investigate similar subjects. The sixth site, How do Mirrors Reflect Light (6), is maintained by the UK Department of Education and Skills on their Standards pages. Educators will find information on various activities, their objectives and expected outcomes, downloads, and other additional material related to light and mirrors. Next, from the Molecular Expressions Web site comes the Multiple Images (7) interactive learning activity. Users get to choose various angles of two adjacent mirrors to see how the image of a pencil changes. Although the activity is brief, it does a good job of illustrating the concept and is actually part of an extensive site that is also worth exploring. The last site related to mirrors is an article written by Dr. Charles Lee of the Air Force Office of Scientific Research called "Perfect" Mirror Design Technology (8). The piece describes a new technology that can reflect light at any angle with virtually no energy loss, as well as its anticipated applications.
