Experiment: Speed of sound in air (115 V, 50/60 Hz)

Experiment: Speed of sound in air (115 V, 50/60 Hz), 8000568 [UE1070320-115], Acoustics
Objective: Generate and measure standing sound waves in Kundt’s tube ..

Thematic focus: ..
• Generate standing waves in Kundt’s tube with both ends closed off.
• Measure the fundamental frequency as a function of the length of the Kundt’s tube.
• Measure the frequencies of the fundamental and overtones for a fixed length of tube.
• Determine the speed of propagation of the wave from the resonant frequencies.

Experiment description: ..
Sound waves propagate in gases in the form of longitudinal waves. The overall velocity is equivalent to the phase velocity. In this experiment a standing wave is generated inside Kundt’s tube with both ends closed off. The fundamental frequency is measured as a function of the length of the tube, and the frequencies of the fundamental and overtones are also measured for a fixed length of tube.
