Describes and apparatus designed to generate and detect pulsed ultrasonics in solids and liquids over the frequency range 1-20 MHz. Experiments are suggested for velocity of sound, elastic constant and ultrasonic attenuation measurements on various materials over a wide temperature range. The equipment should be useful for demonstration purposes.…

Describes a simple photometer capable of measuring small light intensities over small areas. The inexpensive, easy-to- construct instrument is intended for use in a student laboratory to measure the light intensities in a diffraction experiment from single or multiple slits. Typical experimental results are presented along with the theoretical…

Reviews the techniques used by Rutherford in his experiments on thorium, and suggests ways for repeating and re-examining the experiments by capable sixth-form physics students. (LC)

Describes an experiment studying a free falling object which reaches terminal velocity quickly due to air resistance. The mathematical analysis includes some calculus. (TS)

This exercise, suitable for an advanced undergraduate physical chemistry lab, examines the detailed theoretical description of a chemical reaction. Mathematical techniques of moderate complexity serve to introduce some aspects of theoretical chemistry. (Author/TS)

While designed for a senior undergraduate laboratory, the experiment illustrates the principles involved in the various Doppler techniques currently used in nuclear lifetime studies and demonstrates the versatility of the Ge(Li) detector in applications other than direct energy or intensity measurement. (Author/TS)

Describes nuclear teaching experiments and their distribution within the undergraduate curriculum. In addition, sources of information on published nuclear teaching experiments and on the supplier's of nuclear instruments, radiochemical and miscellaneous special materials are identified. Approximate costs for selected nuclear instrument systems…
