wave_mechanics critical_thinking Question 7
Question: In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1 m. when this length is changed to 0.35 m, the same tuning fork resonates with the first overtone. Calculate the end correction
[IIT-JEE (Screening) 2003]
Options:
A) 0.012m
B) 0.025m
C) 0.05m
D) 0.024m
Show Answer
Answer:
Correct Answer: B
Solution:
Let x be the end correction then according to question.
$ \frac{v}{4(l _{1}+x)}=\frac{3v}{4(l _{2}+x)}\Rightarrow x=2.5 $
$ cm=0.025 $
$ m $ .
