535-535.6 1953 EDUCATIONAL FILM GUIDE LIGHT AND SHADOW — Continued Discusses transmission and reflection of light rays, and defines such terms as transparent, transluscent, opaque, and luminous LC card FiA 52-452 EFLA evaluation card No. 755 LIGHT CONTROL THROUGH POLARIZA TION. PolaroidCorp 1946 15min sd b&w free -loan 535 Jh-sh-c-ad A 20 -minute color version also available for free -loan Describes and illustrates the principles of polarization and many of the products the Polaroid Corporation manufacturers based on these principles LIGHT WAVES AND THEIR USES. EBF 1937 llmin sd b«&w $50, rent $2.50 535 Jh-sh-c Guide Produced by Erpi Classroom Films, Inc. An explanation of the principles of reflection with plane, concave, and convex mirrors. Refraction is presented in connection with lenses and with special reference to the human eye. The principles and applications of interference are portrayed. Sequences follow on polar screens, the electromagnetic spectrum, and the quantum theory LC card FiA 52-2307 MEASUREMENT OF THE SPEED OF LIGHT. McGraw-Hill 1952 6%min sd b&w (College physics ser) $37.50 535 c Produced in collaboration with the Visual Aids Committee of the American Assn. of Physics Teachers The toothed -wheel method of Fizeau is described in detail, with the aid of a moving light beam. A modiflcation of this method, due to Michelson, is explained by reflecting the light beam from a rotating eight-sided mirror. The motion is slow enough so that the path of light may be understood at all times Review: Ed. Screen, Nov. 1952, p390 NATURE OF LIGHT. Coronet 1948 lOmin sd b&w $50, color $100 535 * Jh-sh-c-ad Guide Educational consultant: Ira M. Freeman Takes students on a flshing trip with two boys who study light as a form of radiant energy, closely observe the principles of reflection and refraction, and learn how these principles are applied to the science of optics — the way in which all things in nature are affected by the nature of light EFLA evaluation card No. 546 REFRACTION. UW-Educ 1951 8min sd b&w (Light series) $40 535 * Jh-sh-c Produced by Gaumont-British Instructional Films. Re-edited and American narration added by United World Films The law of refraction Is demonstrated and explained by the analogy of wheels, moving from a smooth surface into sand. Several examples of refraction are shown and explained. Critical angle and total internal reflection are demonstrated and explained. Their applications in the submarine periscope and binoculars are explained. The law and its application Is summarized LC card FiA 52-2403 SHADOWS AND ECLIPSES (reflection). UWEduc 1951 lOmin sd b&w (Light series) $45 535 * Jh-sh-c Produced by Gaumont-British Instructional Films. Re-edited and American narration added by United World Films A series of demonstrations Illustrate some sources of light and the properties of light. By means of animated diagrams the formation of shadows and eclipses is explained. Actual photographs of recent eclipses are used to show the sun in total eclipse, the sun's corona, the earth's shadow moving across the moon. The law of reflection is demonstrated and the properties of images in plane mirrors are illustrated and explained LC card FiA 52-2404 SPHERICAL MIRRORS. UW-Educ 1951 13min sd b&w (Light series) $55 535 * Jh-sh-c Produced by Gaumont-British Instructional Films. Re-edited and American narration added by United World Films By demonstration, the characteristics of concave and convex mirrors are explained. The properties of images formed by spherical mirrors are presented by animated diagrams and examined in detail. Characteristics of real and virtual Images are contrasted by studying their formation when objects are placed in different positions. Finally, practical applications of spherical mirrors are illustrated LC card FiA 52-2405 535.6 Color THE CASE FOR COLOR. duPont 1950 25min sd color free -loan 535.6 Jh-sh-c-ad Produced by the Calvin Co. To demonstrate the importance of choosing the right colors, as well as some of the psychological effects which color has on people, three case histories are presented. These involve as elementary classroom, an accounting ofiice, and a restaurant. The fllm first shows what happened when color was misused, and then what happened after the same places were painted according to the principles of 'color conditioning' COLOR CONDITIONING. duPont 1946 22min sd color free-loan 535.6 * ad Produced by Calvin Co.

GenElectric 1941 lOmin sd color freeloan 535.6 sh-c-ad Introduced by scenes of color in nature. Then shows how science has studied color by means of the recording photoelectric spectrophotometer, or color analyzer. Shows how accurate curves for every possible color are used to match colors exactly NATURE OF COLOR. Coronet 1946 18min sd color $80 535.6 * el-Jh-sh-c-ad Guide Educational consultant: Ira M. Freeman, Rutgers University Defines color as the mental reactions to varying wave lengths of visible light. Leads the student in logical, understandable sequence through an explanation of the nature of color in physical terms. Includes application of scientific color principles in the arts, color printing and photography Evaluation in Ed. Screen, Nov. 1946, p524 THIS WORLD OF COLOR.
