Question

An open organ pipe has a fundamental frequency of 262 Hz at room temperature (20 degrees Celsius). What is the length of the pipe?

Answer 1

The answer is supposedly 0.66 m and I don't know how they got it.. o.o

Answer 2

you know the relation between the radius of pipe, length and frequency?? I can't find on internet.

Answer 3

no, I don't.. but I found a few info on this website: http://www.nou.edu.ng/noun/NOUN_OCL/pdf/pdf2/phy203%20OSCILLATIONS%20AND%20WAVES%202.pdf

Answer 4

pardon?

Answer 5

you know the page no??

Answer 6

ohh

Answer 7

I believe 206

Answer 8

fundamental frequency means n=1

Answer 9

ohh, does it also mean \[f _{0}\]? and then what?

Answer 10

we know the velocity of sound right?? 335mps for 20C

Answer 11

oh, 334 m/s for 20 C

Answer 12

we know the L = wavelength / 4
