Describes construction of a variety of relatively inexpensive cameras for astronomical purposes. (CP)

Discussed are strobe photography, making a storage unit, improving a lecture-table meter, and making an electrical discharge tube. (RH)

Photographs illustrate several principles of physics which can be observed in everyday situations. (CP)

Details a method of taking short interval photography with inexpensive equipment. (CP)

Stresses the importance of effective visual aids in physics instructions and the creation of motion pictures through animation. (CP)

Describes a method of making simple transmission gratings by photographing the interference fringes generated by an interferometer. (SL)

Describes high-speed photographic methods used to demonstrate that the tip of a snapped towel does break the sound barrier. (ZWH)

Recommends that teachers make use of the motivation that many young people devote to hobbies. Gives examples of this approach including the study of force, speed, work, power and various electrical concepts with model trains; acceleration and velocity with rocketry; focal length, magnification, field of view with astronomy and photography. (GS)

Describes a physics course, Biomechanics, designed for physical education majors, where stroboscopic photography is used to provide student data to calculate average velocities of objects in different sport activities. (GA)

Describes the use of a microcomputer as an intervalometer for the control and timing of several flash units to photograph high-speed events. Applies this technology to study the oscillations of a stretched rubber band, the deceleration of high-speed projectiles in water, the splashes of milk drops, and the bursts of popcorn kernels. (MDH)

Describes a photogate electronic flash trigger that synchronizes flash discharge with high-speed events. Presents a photographic study of a high-speed collision demonstrating the passage of a BB through an elastic strip. Provides the schematic of the delay circuit utilized in the trigger. (MDH)
