Neco Model Questions Vol1 2023 Physics Question 25
Practice objective / multiple choice question 25 from the 2023 Neco Model Questions Vol1 Physics examination.
A string of length \(L = 1.20\ \text{m}\) fixed at both ends has a linear mass density \(\mu = 0.005\ \text{kg m}^{-1}\). Two harmonic waves travelling in opposite directions on the string have frequencies \(f_1 = 120\ \text{Hz}\) and \(f_2 = 124\ \text{Hz}\), producing a standing‑wave pattern. Assuming the two frequencies correspond to successive normal modes of the string, determine the tension \(T\) in the string.
