Gce Model Questions Vol1 2024 Physics Question 7
Practice objective / multiple choice question 7 from the 2024 Gce Model Questions Vol1 Physics examination.
A source emits sound of unknown frequency \(f_{s}\) and moves towards a stationary observer at \(30\ \text{m s}^{-1}\). Simultaneously the observer moves away from the source at \(20\ \text{m s}^{-1}\) along the same line. The speed of sound in air is \(340\ \text{m s}^{-1}\). The observer hears a frequency of \(660\ \text{Hz}\). Determine the emitted frequency \(f_{s}\) (in Hz) to the nearest hertz.
