VLab - Speed of Sound in Air (Free)

3D virtual lab work for modern physics lessons (section: Mechanics)

PURPOSE: Simulation performance of laboratory works on general physics.

OBJECTIVE: Measuring the propagation time of sound pulses in Kundt’s tube.

SUMMARY: Sound waves propagate longitudinally in gases. The group velocity here is equal to the phase velocity. In this experiment, we will measure the propagation time of a sound pulse between two microphone probes in Kundt’s tube, and use the result to calculate the speed of sound. The temperature dependence of the speed of sound is examined between room temperature and 50°C. The measurement result matches the result of Laplace’s derivation.
