| 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. |
