MHT CET 2022 Physics question
A pipe closed at one end and pipe open at both ends are vibrating in second overtone. They are in resonance with a given tuning fork. The ratio of the length of pipe to that of pipe (Neglect end correction)
Answer: (B)
Solution
Both pipes resonate with the same fork, so the frequency (and hence ) is the same. Closed pipe, second overtone = 5th harmonic: . Open pipe, second overtone = 3rd harmonic: . Equating, , so $ =
