Igcse Model Questions Vol1 2019 Physics Question 21
Practice objective / multiple choice question 21 from the 2019 Igcse Model Questions Vol1 Physics examination.
A pipe closed at one end and open at the other has a length of \(1.2\) m. The speed of sound at \(20^{\circ}\)C is \(340\) m s\(^{-1}\). When the temperature is raised to \(60^{\circ}\)C, the speed of sound changes proportionally to \(\sqrt{T+273}\). Calculate the increase in the fundamental frequency of the pipe, in hertz, to one decimal place.
