Abstract | 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. |
