Describes an empirical method for tuning a piano by matching measured fundamental frequencies to values determined using a pocket calculator. (Author/GA)

Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Describes techniques and equipment intended to both improve laboratory measurements and also form a background for more advanced work by introducing the concepts of electronic and digital circuits. (GS)

Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

Discusses the calibration of bolometric and photoelectric devices utilized for the measurement of solar energy. (SL)

Describes a ripple tank demonstration that displays interference patterns responsible for producing beats and provides photographs of computer simulations of various beat interference patterns. Includes programs for the computer simulation and equations of constructive interference paths in beat interference patterns. (Author/SK)

An advanced undergraduate laboratory experiment in inelastic electron tunneling spectroscopy is described. Tunnel junctions were fabricated, the tunneling spectra of several molecules absorbed on the surface of aluminum oxide measured, and mode assignments made for several of the prominent peaks in spectra using results obtained from optical…

Describes a low-cost instrument using a solar cell as a sensor to measure both instantaneous and integrated value of solar flux. Constructing and calibrating such an instrument constitutes an undergraduate experimental project, affording students an opportunity to examine a variety of aspects associated with solar energy measurements. (Author/SK)

A description is given of an inexpensive nuclear magnetic resonance (NMR) spectrometer suitable for use in advanced laboratory courses. Applications to the nondestructive analysis of the oil content in corn seeds and in monitoring the crystallization of polymers are presented. (SK)
