Question

An organ pipe is 84 cm long and at a temperature of 20 degrees C. What is the fundamental (in Hertz) if the pipe is closed at one end

thanks!

Answer 1

A pipe closed at one end has a fundamental wavelength equal to four times the pipe length. That would be 336 cm. or 3.36 m.

Divide the speed of sound by that wavelength to get the frequency.

Answer 2

awesome, that is what i did but i left out the 4 by mistake. thank you so much!!!!!! :) i really appreciate the help!
