Waves and Sound, An Experiment that Walks.
Brunschwig, Fernand
An experiment on sound waves, developed for non-science majors in a college physics course, is described. The student investigates the interference of two sound waves and measures and wavelength as he uses a prerecorded tape and a cassette player. The student is tutored by the cassette tape recorder, which also produces the overlapping sound waves. The prerecorded monolog for each of the 13 frames for this experiment is presented in this report. Additional equipment utilized for the experiment includes a ruler, a mirror, an extension speaker, and a speaker cord. The results of using this experiment with 70 non-science students are considered and indicate that the students learned a substantial amount of physics from the experiment, with 65 percent of the student reports judged to be good or excellent, showing marked improvement in attitude toward sound wave experiments.
