Describes an experiment in which a recycling oscillator has been designed having a fiber optic data link that closes the loop. Outlines the use of this wink-around system to determine the speed of light and suggests additional application for measuring integrated circuit propagation delays to subnanosecond resolution. (GS)

Describes a laboratory experiment in which the experimental data agree well with the empirical law. Demonstrates that transparent materials reflect light. (CP)

Describes experiments for determining the dielectric constants of liquids and measuring capacitor dissipation. (SL)

Details construction of an inexpensive electronic auditory device in which the resistance in parallel with the device is inversely proportional to the frequency of sound produced. (CP)

Describes the use of storage oscilloscopes in five physics experiments, in lecture demonstrations, and in improved measurement techniques. (GS)

Describes a laboratory demonstration that can be used to convert an analog quantity into frequency, which can then be converted into a binary measure using either an oscilloscope or a frequency counter. (MA)

Describes a one-quarter introductory electronics course in which the students use a variety of inexpensive integrated circuits to design and construct a large number of useful circuits. Presents the subject matter of the course in three parts: linear circuits, digital circuits, and more complex circuits. (GS)

Advocates a strong emphasis on the teaching of the design of electronic circuits in undergraduate courses. An instructional paradigm involving the design and construction of a single-transistor amplifier is provided. (CP)

Describes the experimental procedure used in determining the lifetime of tantalum-181. (CP)
