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!

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