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

Thematic focus: ..
• Measuring the propagation time t of a sound pulse in air at room temperature as a function of the distance s between two microphone probes.
• Confirming the linear relationship between s and t.
• Measuring the propagation time t of a sound pulse in air as a function of the temperature T over a fixed distance between two microphone probes.
• Determining the speed of sound (group velocity) as a function of temperature.
• Comparing the result with Laplace’s derivation.

Experiment description: ..
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.

Additionally recommended: a variety of technical gases
