MHT CET 2026 Physics question
When open pipe is closed from one end then second overtone of closed pipe is higher in frequency by 100 Hz than first overtone of open pipe. The fundamental frequency of open end pipe will be (Neglect end correction)
Answer: (A)
Solution
Let the open pipe have fundamental . Its first overtone is the second harmonic, . Closing one end (same length ) gives a closed pipe with fundamental ; only odd harmonics exist, so its second overtone is the fifth
