Product Description

Experiment speed of sound in air (230 V, 50/60 Hz)

Objective: measurement of propagation time of sound pulses in a Kundt tube
< p> sound waves propagate longitudinally in the exhaust. Here is a speed equal to the speed phase. In this experiment we will measure the pulse propagation time between the two probes healthy microphone in Kundt tube and use the result to calculate the speed of sound. The effect of temperature on the speed of sound tested at a temperature from room temperature to 50 ° C. The measurement is in accordance with the output result of Laplace.

addition is recommended: a variety of technical gases
