Gce Model Questions Vol1 2018 Physics Question 1
Practice objective / multiple choice question 1 from the 2018 Gce Model Questions Vol1 Physics examination.
A source emits a sound of frequency \(500\ \text{Hz}\). An observer moves directly towards the source at a constant speed of \(20\ \text{m s}^{-1}\) and hears a frequency of \(560\ \text{Hz}\). When the observer then moves directly away from the stationary source at the same speed, the heard frequency is \(440\ \text{Hz}\). Assuming the speed of sound in air is constant, determine the speed of sound \(v\) in the medium (in \(\text{m s}^{-1}\)).
