Neco Model Questions Vol1 2017 Physics Question 43
Practice objective / multiple choice question 43 from the 2017 Neco Model Questions Vol1 Physics examination.
A pipe closed at one end has a length of \(0.75\;\text{m}\). When a tuning fork of unknown frequency is placed near the open end, the pipe resonates in its fundamental mode.\n(i) Determine the frequency of the tuning fork, assuming the speed of sound in air is \(340\;\text{m s}^{-1}\).\n(ii) The same pipe is then filled with a gas in which the speed of sound is \(410\;\text{m s}^{-1}\), and the same tuning fork now produces the first overtone (second harmonic) of the pipe. Find the frequency of the tuning fork that would be required to produce this overtone in the new gas.
