If we study the vibration of a pipe open...

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

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.

Text Solution

Verified by Experts

The correct Answer is:
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.
