An electron-spin-resonance experiment which has been successfully performed in an advanced undergraduate physics laboratory is described. A discussion of that part of the theory of magnetic resonance necessary for the understanding of the experiment is also provided in this article. (DT)

A laboratory instructional program involving metal-insulator-semiconductor (MIS) devices is described. In the first of a two-part experiment, students become familiar with the important parameters of a simple MIS device and learn measurement techniques; in the second part, device fabrication procedures are learned.

Describes an experimental arrangement for investigating optical barrier penetration. (SL)

Describes an experiment demonstrating the frustration of totally reflected visible light. (SL)

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

Describes an experimental arrangement which provides a simple introduction to holographic interferometry. (SL)

Presents simple and inexpensive demonstrations of properties of metallic glasses. (SL)

Describes an experiment for determining the blackbody radiation constant hc/k, utilize a conventionally built cavity and a single-beam, single-window Perkin-Elmer 12-C model spectrometer. (SL)

Described is an advanced undergraduate physics laboratory experiment for determining an area, and bandwidth-independent parameter, D* ("dee star"), of an infrared detection devices' detectivity. (SL)

Reviews the Hafele-Keating experiment on relativistic changes in eastward and westward moving cesium atomic clocks. Recommends the use of the Sagnac effect to remove the east-west time asymmetry and of the general-relativistic effect to elucidate the clock-rate changes. (CC)

The ratio of electronic charge to Boltzmann's constant can be easily determined by measuring the short-circuit collector current versus the emitter-base voltage characteristic of a silicon transistor connected in the common-base mode. (Author/DF)

Describes the theoretical principles and experimental arrangement in determining the transmission and reflection coefficients for polarizations which are parallel and perpendicular to the plane of incidence. Indicates an error of the order of five percent in the results obtained. (CC)

Describes a student experiment in which a pendulum is swung through angles up to 160 degrees by suspending it on a solid rod. Graphical analysis is used for empirically determining parameters. (MLH)
