1.	If we study the vibration of a pipe open at both ends, then the following statements is not trueA. Open end will be antinodeB. Odd harmonics of the fundamental frequency will be generatedC. All harmonics of the fundamental frequency will be generatedD. Pressure change will be maximum at both ends.
Answer» Correct Answer - D When pipe is open at both ends then ratio of frequency (i) `v:2v:3v:4v:5v` where `v=(v)/(2L)` odd and even both harmonics will present So, option (1), (2) and (3) are correct. `therefore ` pressure variation is minimum at antinode `therefore` (4) is wrong option.
