Explores some of the principles behind the working of fluorescent bulbs using a specially prepared fluorescent bulb with the white inner fluorescent coating applied along only half its length. Discusses the spectrum, the bulb plasma, and light production. (JRH)

Describes the use of carbide lights as an excellent mechanism for introducing or reviewing many basic chemistry concepts including elements and compounds, endothermic and exothermic reactions, physical and chemical changes, and balancing chemical equations. (JRH)

Presents a demonstration that uses a laptop computer as a source of polarized light to make clear the principle behind a liquid-crystal display (LCD). (JRH)

Presents the theory behind the spots of light observed inside a balloon when it is exposed to light. Discusses the use of this phenomenon in teaching optics lessons. (JRH)

Describes a method to trace the reflection of a light ray incident on a pair of mirrors hinged together along one edge. Can be extended to ray tracing through tubes, cones, and prisms. (JRH)

Describes a method to combine two learning experiences--optical physics and matrix mathematics--in a straightforward laboratory experiment that allows engineering/physics students to integrate a variety of learning insights and technical skills, including using lasers, studying refraction through thin lenses, applying concepts of matrix…

This book contains scaled-down versions of Exploratorium exhibits that teachers can make using common, inexpensive, easily available materials. Each topic begins with a drawing of the original full-sized exhibit on the museum floor, a photograph of the scaled-down version which contains an introduction to the exhibit, a list of materials needed…

Discusses the following questions based on the assumption that students' personal experiences and prior beliefs about plane mirrors can promote interesting discussions: (1) How mirror images are formed? (2) Why doesn't paper behave like a mirror? (3) Does a mirror left-right reverse objects? and (4) Why are corner images of two perpendicular…

This is a textbook of Fourier optics for the classroom or self-study. Major topics included in the 38 chapters are: Huygens' principle and Fourier transforms; image formation; optical coherence theory; coherent imaging; image analysis; coherent noise; interferometry; holography; communication theory techniques; analog optical computing; phase…

The Moire pattern is the shimmering pattern which looks like an odd interference pattern in window screens or folds of nylon shower curtain. Illustrates some of the ways the effect may be used, including demonstration of wave interference, detection of small displacement, persistence of vision, contour measurement, beats, and optical clearness.…

Eleven demonstrations of light polarization are presented. Each includes a brief description of the apparatus and the effect demonstrated. Illustrated are strain patterns, reflection, scattering, the Faraday Effect, interference, double refraction, the polarizing microscope, and optical activity. (CW)

Presents two demonstrations to compare the differences between the screen reproductions of a bulb when using a converging lens and a pinhole and how that reproduction image reaches the observer's eye from multiple vantage points. (MDH)

Describes simple and inexpensive labs for introducing students to fiber optic communications. Students investigate light as a carrier wave; look into the difficulties associated with "light" communication; and learn about modulation, optical fibers, and critical angles. (PR)

Opportunities to learn and discover surround a young child every day. The activities and ideas within this book have been formulated to encourage a child's natural curiosity and sense of wonder and to engage all the child's senses in learning and discovery. The activities focus on the child as a natural explorer and involve children in identifying…

Discusses a demonstration of interference phenomena using three sheets of polaroid material, a light source, and a light meter. Describes instructional procedures with mathematical expressions and a diagram. (YP)
