KUNDT TUBE PDF

An apparatus designed by August Kundt —94 in to measure the speed of sound in various fluids. It consists of a closed glass tube into which a dry powder such as lycopodium has been sprinkled. The source of sound in the original device was a metal rod clamped at its centre with a piston at one end, which is inserted into the tube. When the rod is stroked, sound waves generated by the piston enter the tube.

Any waves traveling along the medium will reflect back when they reach the end creating a standing wave allowing harmonics to be identified. Nodes occur at fixed ends and antinodes at open ends. Furthermore, it provides an insight into the interesting phenomenon of standing sound waves. In this experiment the amplitude of the sound wave can be observed at different locations in the tube, allowing a half wave length to be measured between an adjacent maximum and minimum.

Here, one-side closed cylindrical transparent pipe filled with air is used as a resonator. One end of the tube is attached with a loudspeaker where as the other end is fixed with a movable piston with reflector and a microphone. An AC voltage applied to the loudspeaker, tunes the membrane to vibrations that are transferred to the gas or air column. Frequency can be changed by enlargement or diminishment of the glass cylinder as well as by changing the frequency of the generator.

A sine wave from an audio oscillator and the signal picked up by a movable microphone to produce Lissajous figures and determine the speed of sound.

Kundt's Tube E

Kundt's tube is an experimental acoustical apparatus invented in by German physicist August Kundt [1] [2] for the measurement of the speed of sound in a gas or a solid rod. The experiment is still taught today due to its ability to demonstrate longitudinal waves in a gas which can often be difficult to visualise. It is used today only for demonstrating standing waves and acoustical forces. The tube is a transparent horizontal pipe which contains a small amount of a fine powder such as cork dust, talc or Lycopodium.

Longitudinal Waves - Kundt's Tube

Sound in air is propagated only by means of longitudinal waves; waves in which the particle's motion consists of oscillations back and forth in the direction of propagation. In a solid such as a metal rod, sound can be transmitted either by longitudinal or transverse waves. In this experiment, longitudinal sound waves will be produced in a metal rod and an air column. Using the properties of wave motion, the frequency of the sound and the speed of sound in the rod can be determined. The apparatus consists of a glass tube supported on a metal base as shown in the diagram. A clamp at one end of the base holds a metal rod which has a metal disk attached to one end. The rod and disk extend inside the glass tube, whose position can be adjusted to center the tube about the disk.
