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.
