Questions
A closed organ pipe of length L and an open organ pipe contain gases of densities and respectively. The compressibility of gases are equal in both the pipes. Both the pipes are vibrating in their first overtone with same frequency. The length of the open organ pipe is
detailed solution
Correct option is C
Frequency of first over tone of closed pipe = Frequency of first over tone of open pipe ⇒3v4L1=vL2⇒34L1γPρ1=1L2γPρ2 ∵v=γPρ⇒L2=4L13ρ1ρ2=4L3ρ1ρ2Talk to our academic expert!
