What pitch would u ld be produced by a pipe with a length of 1.2 ft?

Question

The length of a panpipe p (in feet) is inversely proportional to it's pitch l (in Hertz). The inverse variation is modeled but the equation p= 495/l

Answer 1

p = 495 / l

p = 495 / 1.2

p = 412.5

 

Between middle G and G# on the piano. 

Answer 2

495/1.2 = 412.5

 

A G#/Ab is 415, so it would be a slightly flat G#/Ab.
