Sonometer
Used to verify the laws of vibrating strings, frequency
comparison with vibrating bodes and determination of the frequency of a
tuning fork by tuning a sting in union with it. It utilizes the
basic design of the violin, bass, guitar and piano. There is a
hollow wooden
resonance chamber (155" x 12" 8
cm) and strings are stung across it. However these are mounted
so that they may be used for some serious science experiments. One
end of a brass and steel wire is fixed to one edge of the resonance
chamber. The other end is secured with a pegged tensioning key.
Start by adjusting the string tension so that it produces the same note as
a tuning fork. If you are really good at it, then try it with a musical
instrument. But the Sonometer doesn't stop there. A pulley and
hook are provided for the third steel wire which can be tensioned by
masses so that you can determine the necessary tension. Comes with two
steel wires and a brass wire. They are easy to break but can be
easily replaced at any guitar or piano store. Two meter scales graduated in millimeters.
