Principle

In this experiment, the students determine the velocity of sound in air. For this purpose, they measure the difference in the propagation time of a sound signal of two spatially offset stereo loudspeakers with the "measure Acoustics" software.

Benefits


Experiment is part of an experiment set with a total of 22 experiments about generation, propagation and perception of sound, oscillations and waves

Particularly appropriate as an experiment for first contact with physics in general

With graphic student worksheets

With detailed instructor information

Optimized for tight schedules, i.e. minimum preparation time required


Tasks

We all know that during a thunderstorm, sound propagates with a limited velocity. We see the flash of lightning but the thunder does not follow until several seconds later, depending on the distance. In this experiment, determine the velocity of sound in air with the aid of stereo loudspeakers and a microphone.
