MHT CET 2026 Physics question
When open pipe is closed from one end then third overtone of closed pipe is higher in frequency by 150Hz than second overtone of open pipe. The fundamental frequency of open end pipe will be (Neglect end correction)
Answer: (D)
Solution
Let the pipe length be and the open-pipe fundamental . Second overtone of the open pipe . When closed at one end the fundamental is and only odd harmonics exist; the third overtone is the 7th harmonic, .
