Two open pipes of different lengths and of same diameter in which the air column vibrates with fundamental frequencies ' 
' and ' 
' respectively. When both pipes are joined to form a single pipe, its fundamental frequency will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
For open pipe, 
where 
is the fundamental frequency, 
is the velocity of sound in air and 
is the length of the open pipe.
and 
When both open pipes are joined to form a single pipe with both ends open then, the fundamental frequency will be
