Gce Model Questions Vol1 2025 Physics Question 49
Practice objective / multiple choice question 49 from the 2025 Gce Model Questions Vol1 Physics examination.
A source of sound of frequency \(f_{s}=800\ \text{Hz}\) moves directly towards a stationary observer at a speed of \(30\ \text{m s}^{-1}\). At the same time a second identical source (also \(800\ \text{Hz}\)) remains stationary, while the observer moves directly away from it at \(20\ \text{m s}^{-1}\). The speed of sound in air is \(v=340\ \text{m s}^{-1}\). Find the beat frequency heard by the observer due to the superposition of the two sounds.
