Igcse Model Questions Vol1 2022 Physics Question 5
Practice objective / multiple choice question 5 from the 2022 Igcse Model Questions Vol1 Physics examination.
A pipe that is open at one end and closed at the other has a length of \(1.20\) m. The speed of sound in air at the experimental temperature is \(340\) m s(^{-1}\). The pipe resonates at its third harmonic (first overtone).\n\n(a) Calculate the frequency of this resonance.\n(b) If the pipe is heated so that the speed of sound increases by \(5\)% while the length remains unchanged, what is the new frequency of the same harmonic? Give both frequencies to the nearest hertz.
