The length of an organ pipe is 19.48
Given,
An organ pipe that is open on both ends and has a fundamental frequency of n1 = 8.75Hz & the speed of sound in air is v = 341m/s
we have the formula for fundamental frequency in open pipe as
n1 = v /λ1 = v / 2L
so L = v / 2n1
plug in the values for L
n1 = v / λ1 = v / 2L
L = v / 2n1
= 341 / 2 (8.75)
= 19.48
The length of an organ pipe is 19.48
