Resonance tube Experiment for GSEB students of std 11 and 12, physics practical

Resonance tube Physics practical.
Resonance tube practical







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).

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 

Resonance tube practical reading 
Resonance tube practical reading 
(1)  f1 / f2 = l2 / l1

(2)  f3 / f4 = l4 / l3
