Neco 2023 Physics Question 1
Practice objective / multiple choice question 1 from the 2023 Neco Physics examination.
A string of length L is fixed at both ends. When a tension of \(80\ \text{N}\) is applied, a standing wave with three complete loops is observed. When the tension is increased to \(180\ \text{N}\), the string shows four complete loops and the frequency of vibration is \(120\ \text{Hz}\). Assuming the linear mass density of the string remains unchanged, calculate the fundamental frequency of the string under the original tension of \(80\ \text{N}\).
