RESONANCE TUBE Pr-19
AIM :-
To compare the frequencies of two tuning forks using a resonance tube and to find the end-correction. Repeat the experiment for two other tuning forks .
Find the lengths (l) of the resonating air columns for tuning forks of five different frequencies.
Draw a graph of 1 / f --
APPARATUS :-
A metallic tube open at both the ends (known as resonance tube),
a cylinder( of glass or metal) for filling water, a stand,
a meter rule,
a rubber-pad and tuning forks( two of known frequencies and two of unknown frequencies).
OBSERVATION TABLE :-
(1) Least count of the vernier callipers = cm
(2) Internal diameter of the resonance tube : d1 = cm; d2 = cm
Average diameter d = cm
(1) f1 / f2 = l2 / l1
(2) f3 / f4 = l4 / l3
