If we study the vibration of a pipe open at both ends, then the following statements is not true

Options

A. Open end will be antinode
B. Odd harmonics of the fundamental frequency will be generated
C. All harmonics of the fundamental frequency will be generated
D. Pressure change will be maximum at both ends.

Answer

D

Explanation

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.
