Neco 2017 Physics Question 2
Practice objective / multiple choice question 2 from the 2017 Neco Physics examination.
A tube closed at one end has a total length of \(1.00\ \text{m}\) at \(20^{\circ}\text{C}\). The speed of sound in air varies with temperature as \(v = 331 + 0.6T\) (m\,s\(^{-1}\)), where \(T\) is in degrees Celsius. The tube is filled with water to a height \(h\) from the closed end, leaving an air column of length \(L_{\text{air}} = 1.00 - h\). The air column resonates at its fundamental frequency of \(256\ \text{Hz}\). Find the water height \(h\) (in metres) in the tube.
