Neco 2023 Physics Question 18
Practice objective / multiple choice question 18 from the 2023 Neco Physics examination.
Two tuning forks of frequencies \(256\ \text{Hz}\) and \(260\ \text{Hz}\) are sounded together, producing beats. A stretched string fixed at both ends vibrates at its fundamental frequency equal to the average of the two fork frequencies. If the speed of transverse waves on the string is \(120\ \text{m s}^{-1}\), find (a) the length of the string in metres (to three decimal places) and (b) the beat frequency in hertz.
