Describes an apparatus (called the "Rainbow Cup") used for demonstrating the colored rings produced by constructive interference in soap films. Discusses construction of the Rainbow Cup and gives hints for its use in the classroom, especially in relation to classroom humidity. (JM)

Recommends using dramatic demonstrations on the energy in chemical systems as an audiovisual adjunct to lectures and laboratory sessions. Lists materials needed and provides procedures including safety tips for various experiments to produce chemical light, heat, and electricity; and concludes with hints for preparation/rehearsal. (JM)

Describes systems which use wireless terminals to communicate with mainframe computers or minicomputers via radio band, discusses their limitations, and gives examples of networks using such systems. The use of communications satellites to increase their range and the possibility of using light beams to transmit data are also discussed. (MBR)

This document defines "photonics" as the generation, manipulation, transport, detection, and use of light information and energy whose quantum unit is the photon. The range of applications of photonics extends from energy generation to detection to communication and information processing. Photonics is at the heart of today's…

Describes method for locating images in simple and complex systems of thin lenses and spherical mirrors. The method helps students to understand differences between real and virtual images. It is helpful in discussing the human eye and the correction of imperfect vision by the use of glasses. (Author/SK)

This review of 11 recent science kits, texts, supplements, and series for various grade levels, K-12, includes a special section examining three junior high level texts on the subject of light. (SJL)

A model of the phenomenon of the desert mirage is presented using Snell's Law and simple programing techniques. Optical trajectories predicted by the model are illustrated. (CW)

Applications of the Landsat Thematic Mapper in the fields of pedology, geology, and geomorphology are described. The history of the Landsat program and Landsat products are discussed. Illustrations of different Landsat views are presented. (CW)

Presents an easily performed experiment to determine sucrose concentrations using a laser and a hollow glass prism. The experiment is suggested for high school, freshman college, and instrumental analysis classes. Notes an Erlenmeyer flask can be used instead of a prism. (MVL)

Provided are hands-on activities on light, simulated emission, light radiation, and common uses of lasers. Directions and materials are discussed. Included is a diagram of a laser model. (CW)

Describes a set of hands-on corridor demonstrations that illustrate various aspects of interference and diffraction of light waves and sound waves. (11 references) (JRH)

Presents a sequence of activities designed to allow eighth grade students to deal with one of the fundamental relationships that govern energy distribution. Activities guide students to measure light bulb brightness, discover the inverse square law, compare light bulb light to candle light, and measure sun brightness. (two references) (MCO)

The directions and diagrams for making a reflecting telescope and a refracting telescope are presented. These telescopes can be made by students out of plumbing parts and easily obtainable, inexpensive, optical components. (KR)

Uses a projector, a prism, and two screens to demonstrate the composition of white light and detect color. (MDH)

Presents a model of a generic atom that is used to represent the movement of electrons from lower to higher levels and vice-versa due to excitation and de-excitation of the atom. As the process of de-excitation takes place, photons represented by colored ping-pong balls are emitted, indicating the emission of light. (MDH)
