The contrabassoon is the wind instrument capable of sounding the lowest pitch in an orchestra. it is folded over several times to fit its impressive 18 ft length into a reasonable size instrument. the actual fundamental frequency of the contrabassoon is 27.5 hz , which should be different from your answer in part a. this means the model of the instrument as an open-closed tube is a bit too simple. but if you insist on using that model, what is the "effective length" of the instrument?

3.12 m

Explanation:

The fundamental frequency of an open-closed tube is given by

where

f1 is the fundamental frequency

v is the speed of sound in air (343 m/s)

L is the length of the tube

If we use the model mentioned, we can consider L to be the effective length of the instrument. This means we can re-arrange the formula and use the fundamental frequency, f1 = 27.5 Hz, to find L:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
