 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.
