Sonometer

AIM :-

To study the relation between frequency and the length of a stretched string with the help of a sonometer.

PRECAUTIONS

1  The wire should be of uniform cross-section and there should not be any twist or bend in it.

2   The pulley should rotate without friction.

3   Put that much weight  in the pan so that the deformation produced in the wire should not exceed the elastic limit.

4   The stem of the tuning fork, not its prongs, should be placed on the sonometer box or on the support.

Apparatus:-  A sonometer,  tuning forks ( of frequencies from 256 Hz – 512 Hz),  a pan or a hanger of known weight,  four to five 500 gm weights, a paper rider, a rubber-pad and a meter rule.
