SONOMETER, WOOD, TABLE MODEL
|
For verifying the laws of vibrating strings, frequency comparisons with vibrating bodies, and determination of the frequency of a tuning fork by tuning a string in unison with it.
Consists of a hollow wooden resonance chamber measuring (l x w x h), 115 x 12 x 8cm, with two meter scales graduated in millimeters. One end of a brass and a steel wires is fixed on the edge of the resonance chamber and the other end of the wires are pegged with a tensioning key. Pulley and hook provided for the third steel wire to be tensioned by masses. Two movable bridges are also provided. Weights not included.

KUNDT'S APPARATUS (TUBE)
|
For demonstrating formation of stationary longitudinal waves in air or gases and for determining the wavelength and velocity of sound in metal rods, air and other gases.
Consists of a glass tube about 1000mm long and 30mm in diameter, which is closed at one end with a cork. The tube rests on wedge supports securely fastened by coil springs and mounted on a base. A 90cm long aluminum rod having a terminal disk of diameter slightly less than that of the glass tube acting as a piston in the glass tube. The aluminum rod is rigidly clamped in the middle, on a metal post. Lycopodium powder (not supplied) can be used to show nodal points.
