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 ® l and find the
end-correction
Calculation
(1) The linear density (i.e. mass per unit length) of the wire, m= prrr = .
(2) Calculation of √T/L
(3) The frequency of alternating current f = 1 / 2L √T / m
= 1 /
2 √m * (average √T/L )
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).
