Question about sound frequency of an organ....? 1. The problem statement, all variables and given/known data Based on this picture from the Jehmlich organ manufacturer in Dresden, Germany, estimate the frequency of sound produced by the organ pipe held by the man. Assume that the pipe is a tube open at both ends. http://cache.daylife.com/imageserve/01iq4P0e330tQ/610x.jpg 2. Relevant equations 3. The attempt at a solution I feel like the formula to be used is Fn=n(V/4L)...I am not sure how to estimate length (maybe 1.5 m based on the size of the person?) And ahve no idea what n would be, or if I am evenusing the right formula...any experts...?
