Homework Statement
In the experiment for the determination of the speed of sound using a resonance tube, the diameter of the column tube is 4 cm. The frequency of the tuning fork is 512 Hz. The air temperature is 38° C in which the speed of sound is 336 m/s. The zero of the meter scale coincides with the top end of the resonance column tube. When the first resonance occurs, the reading of the water level is
(a) 14.0 cm (b) 15.2 cm
(c) 6.4 cm (d) 17.6 cm
→ v=336 m/s, f=512 Hz, t=38° C, d=4 cm=0.04 m
Homework Equations
l1+e=(1/4)(v/f)
where l1 is the reading of the water level when the first resonance occurs, and e is the end correction.
Then, l1+e=(1/4)(336/512)=0.1640625 m
The Attempt at a Solution
l1+e=(1/4)(v/f)
where l1 is the reading of the water level when the first resonance occurs, and e is the end correction.
Then, l1+e=(1/4)(336/512)=0.1640625 m
How do I calculate the end correction in order to the water level?
How do I use the given temperature and the diameter of the tube?
