Question

2m long pipe is open at both ends it's harmomic frequency is​

Answer 1

Explanation:

Sound travels at about 340 meters per second.

In an open pipe, the length of the pipe contains half of a wavelength, so a sound of wavelength 4m will be produced.

340 / 4 is 85, so the harmonic frequency will be 85 hz.

Answer 2

340 metres
