Question
An air column L = 1.97 m in length is open at both ends. The frequency of a certain harmonic is 410 Hz, and the frequency of the next higher harmonic is 492 Hz.
%3D
Part 1)
Determine the speed of sound in the air column.
U =
m/s
Part 2)
For the answer you found in part 1, what is the fundamental frequency of the air column if one of its ends were closed?
fi =
Hz
%3D
Part 3) (independent of other parts)
An astronaut on the Moon wishes to measure the local value of g by timing pulses traveling down a wire that has a large mass M kg suspended from one end. Assume the wire is Im
long and has a mass m kg. A pulse requires ts to traverse the length of the wire. Find an expression (algebraic) for g in terms of the other variables given in the problem. (You can neglect
the mass of the wire when calculating the tension in it.)
