Two narrow organ pipes, one open (length 
) and the other closed (length 
) are sounded in their respective fundamental modes. The beat frequency heard is 5 Hz. If now the pipes are sounded in their first overtones, then also the beat frequency heard is 5 Hz. Then:
A
= 
B
= 
C
= 
D
= 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION
(b, c)
fundamental frequency of open pipe, n 0 = 
closed pipe, n C = 
= 5 ...(i)
For first overtone n 0 = 
, n C = 
= 5 ...(ii)
on solving (i) and (ii)
λ 1 = λ 2 ⇒
