An alternative speed of light measurement experiment for a senior laboratory
Parisi, Alfio V. , Mottram, Ken, Kimlin, Michael G., Wilson, Meegan, & Wollstein, A. (1999) An alternative speed of light measurement experiment for a senior laboratory. Australian Science Teachers' Journal, 45(4), pp. 51-53.
A simple, time-of-flight experiment utilising readily available equipment is described for use in a senior school Physics laboratory. A modulated laser is employed with measurements, taken over a number of distances. Students obtain a conceptual understanding for the extremely high, but measurable speed of light. The technique of eliminating an unknown constant by making more than one measurement is also introduced. Additionally, students are introduced to the concepts of optics, measurement of very small time intervals, modulation of lasers, waveform generation, fast detectors and data processing.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
