Gce Model Questions Vol1 2024 Physics Question 29
Practice objective / multiple choice question 29 from the 2024 Gce Model Questions Vol1 Physics examination.
A source emits sound of frequency \(f = 500\ \text{Hz}\) in air where the speed of sound is \(v = 340\ \text{m s}^{-1}\). The source moves towards a stationary observer at \(30\ \text{m s}^{-1}\). After the source passes the observer, the source continues moving away at the same speed while the observer moves away from the source at \(20\ \text{m s}^{-1}\). Determine the frequency heard by the observer after the source has passed and both are moving away from each other. Also give the wavelength of the sound in the medium corresponding to this observed frequency. Give answers to three significant figures.
