The speed of sound is a physical property that can be measured easily in the lab. However, finding an inexpensive and intuitive way for students to determine this speed has been more involved. The introduction of affordable consumer-grade high-speed cameras (such as the Exilim EX-FC100) makes conceptually simple experiments feasible. Since the…

An introduction to satellite meteorology is presented to promote use of live weather satellite photographs in the classroom. Topics addressed include weather satellites, how they work, earth emissions, satellite photography, satellite image analysis, obtaining satellite pictures, and future considerations. Includes sources for materials to…

Describes simple speckle photography experiments which are easy to set up and require only low cost standard laboratory equipment. Included are procedures for taking single, double, and multiple exposures. (JN)

Describes a college level minicourse utilizing photography and the camera to present basic physical optics. Included is an outline of topics and a listing of course objectives. (SL)

Describes a method for determining the exposure correction factors in close-up photography and macrophotography. The method eliminates all calculations during picture-taking, and allows the use of a light meter to obtain the proper f-stop/exposure time combinations. (Author/MLH)

Describes procedure for making X-ray photographs on Polaroid 3000 black and white roll film. (SL)

Presents a low-cost activity in which students dissect cameras and build telescopes. (WRM)

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

A "gedanken photograph" of a relativistic meter stick is analyzed at a level appropriate for undergraduate students. Aspects of the photographic process are analyzed in the frame of the moving meter stick. (Author/SK)

Gives an outline of a physics course for fine arts students majoring in photography and for other nonscience students interested in photography. (MLH)

Describes an inexpensive fog machine that is useful for photography and laser demonstrations. The apparatus uses liquid nitrogen to chill steam to make a fine mist safe for precision optics. The device can be made for around $50. (MVL)

Describes an experiment for recording holograms using a minimum of costly apparatus. Includes a description of apparatus and materials, the procedure for recording the hologram, the processing of the hologram, and the reconstruction of the image. (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)

Described is the phasor method of superposition of waves. The intensity pattern from a system of microwave sources is calculated point by point on a plane corresponding to a film emulsion, and then printed and directly converted to a hologram for 3-cm microwaves. Calculations, construction, and viewing of holograms are included. (Author/DS)
