Described are the purposes, laboratory set-ups, and procedures of four classroom experiments: ultrasound speedometer; vibrating-bar depth gauge; folding three-dimensional model of equipotential surfaces; and a simple optical system for the reconstruction of images from computer-generated holograms. Diagrams and pictures are provided. (YP)

Describes four physics experiments including "Investigation of Box Resonances Using a Micro"; "A Direct Reading Wattmeter, DC or AC"; "Exercises in the Application of Ohm's Law"; and "Hysteresis on Gas Discharges." Discusses procedures, instrumentation, and analysis in each example. (CW)

Describes some undergraduate laboratory experiments in acoustics which involve the analysis of speech and musical instrument sounds and the general analysis of the frequency range of complex sounds. (HM)

Describes a method for the determination of the velocity of sound using a dual oscilloscope on which is displayed the sinusoidal input into a loudspeaker and the signal picked up by a microphone. (GS)

Experiments are designed with application to phenomena of the real world for use in a third-quarter introductory college physics course in wave motion, sound, and light. The computer is used to process and analyze experimental data and to extend experimental observations through simulation. (Author/TS)

Describes an advanced undergraduate physics experiment which permits the measurement of ultrasound velocity and absorption in liquid systems. A description of the tasks the student is expected to perform is also included. (HM)

Presented is an experiment which provides a study both of the end correction involved with open pipes and also of the effect that varying the size of the tone hole in the pipe has on its fundamental frequency. Discussed are equipment, formulas, background, and methods. (CW)

Presents two demonstrations: heatwave focusing by concave reflectors and wave speed on a string. Describes the apparatus, and procedures for the demonstrations. (YP)

Presents a classroom experiment that demonstrates the directional sensitivity of the human ear. Outlines the activity's procedures and provides a diagrammatical view of the experimental arrangement. Also included is an analysis of the expected results. (ML)

Describes three activities: "Solar Approach to Ohm's Law," dealing with the Ohm's law and the inverse square law; "Using LED's to Demonstrate Induced Current," showing Faraday's law and Lenz's law by using light emitting diodes (LEDs); and "The Helium-Filled Organ Pipe," discussing a discrepancy between theory and experiment. (YP)

This book contains 65 physics experiments. The experiments are for a college-level physics course for music and art majors. The initial experiments are devoted to the general concept of vibration and cover vibrating strings, air columns, reflection, and interference. Later experiments explore light, color perception, cameras, mirrors and symmetry,…

Describes three experiments: (1) "Liquid Flow from Orifices"; (2) "Microcomputer-Controlled Investigation of Battery Discharge and Recovery"; and (3) "Measurement of the Speed of Sound." Drawings and diagrams accompany each. (RT)

Six major concepts of science are illustrated through the use of simple, easily equipped hands-on activities. Included in each activity are a list of materials, procedures, questions for students, and suggested discussion. Aquatic acoustics are highlighted. (CW)

Described are four musical instruments constructed from polyvinyl chloride (PVC) pipe. The use of computerized synthesizers to play scales and chords is discussed. Suggestions for other illustrations of acoustics are included. (CW)
