Question

On a day when the speed is 345 m//s, the fundamental frequency of a closed organ pipe is 220 H_(Z) . (a) How long is this closed pipe? (b) The second overtone of this pipe has the same wavelength as the third harmonic of an open pipe . How long is the open pipe ?

Answer 1

Answer:

A::b::c::d

Explanation:

(a) f=ν4l

∴l=ν4f=3454×220

=0.392m (b) 5(ν4lc)=3(ν2lo)

∴lo=65lc=65(0.392)

=0.470m
