Abstract:

Without lenses, vast areas of human knowledge, from astronomy to microbiology, would never have developed - not to mention photography and the movies! This video uses compelling animation sequences and other visuals to explain how convex and concave lenses produce images in a wide variety of situations. After a concise overview of refraction, the program illustrates how magnifying glasses work and how projectors cast images onto cinema screens. It then looks, quite literally, into a tuna fish's eye as a basis for showing how vision works. After further explaining how light travels through concave lenses, the film discusses how corrective eyewear helps people who have vision defects. Viewers are also given a chance to consider aspects of slow motion, fast motion, and stop motion imagery, as well as the mathematics of lenses and image formation.
