Suggests that adequate attention should be given to lattice imperfections in teaching solid state chemistry. Some concepts to be included in such a program are explained. An experiment to be performed by undergraduates on photomicrography is described in detail. (PS)

Illustrated with photographs and poems by participating students. (RD)

Photochemical data are presented to indicate how use of sensitizing dyes extends the spectral range to which the substrate semiconductor is sensitive. Data demonstrate that specific energetic requirements exist for a dye to be an effective sensitizer. Also shows how photooxidation is increased by increasing surface concentration of the dye. (JN)

In August, 1981, National Aeronautics and Space Administration launched Dynamics Explorer 1 into polar orbit equipped with three cameras built to view the Northern Lights. The cameras can photograph aurora borealis' faint light without being blinded by the earth's bright dayside. Photographs taken by the satellite are provided. (JN)

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)

Investigates the "photographic" appearance of a cube moving at relativistic speeds, and shows that it depends upon whether the camera is held fixed with the optic axis perpendicular to the direction of motion or panned to follow the cube as it moves. (Author/GA)

Presents an annotated bibliography of 12 publications dealing with remote sensing of the environment. Included is information on how to obtain aerial and spacecraft photographs and images. (BB)

Describes the topics covered and methods used in a liberal arts astronomy course on photographing the night sky. (MLH)

Various aspects of photography using both transmitted and reflected light microscopy are described. Microscope configuration, preparation of samples for photomicrography, and the use of black/white or color film are discussed. (KR)

The still video camera stores color images on a small, removable disk. Describes several classroom uses of this camera for science instruction. (PR)

In some contexts, a photograph may be worth a thousand words. Previous research revealed a dialectical character of photographs: they simultaneously lack determinacy and exhibit an excess of meaning. The purpose of this study was to understand how, under this condition, high school students interpret photographs that were accompanied by different…

In this NASA publication, the technology behind the art of high-altitude surveying is explained in language understood by high school students. The principles behind ground-based surveys are first explained, then several diagrams are utilized in the explanation of photographic surveys. Additional information is provided concerning the use of…

Described are the planning and execution of a project to record by color slides and video-tape recorders the pertinent learning experiences gained during field trips, so that the information can be made available during periods when it is not practical to repeat the field trips. (SL)

Presented is information to supplement elementary physics texts so that teachers may expand the presentation of classical optics to include some basic concepts related to photographic systems. (SL)
