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.
