Physics Demonstrations in Light is a two-part video program which presents a full range of demonstrations in the areas of geometrical optics, physical optics, and the nature of light. The program was developed in an effort to give physics teachers a comprehensive collection of video demonstrations, supplementing the instructor's live classroom demonstrations. The program was designed to meet the needs of high school physics classes as well as introductory level college physics classes. The selection of demonstrations includes those which are difficult to perform in the classroom and those requiring apparatus not readily accessible to many physics teachers. Detailed observation of the demonstrations is accomplished through use of a filming approach which focuses solely on the apparatus, allowing the teacher to utilize the program in a way which is consistent with his or her personal instructional approach. The voice over narration eliminates the on-screen presenter and allows attention to be directed to the physical behavior being studied.
