The range of human hearing is roughly from twenty hertz to twentykilohertz. based on these limits and a value of 305 m/s for the speed of sound, what are thelengths of the longest and shortest pipes (open at both ends andproducing sound at their fundamental frequencies) that you expectto find in a pipe organ?
1 (shortest pipe)
2 (longest pipe)
