Practice objective / multiple choice question 47 from the 2018 Neco Model Questions Vol1 Physics examination.
A source of sound moves in still air (speed of sound \(v = 340\ \text{m s}^{-1}\)). When the source approaches a stationary observer, the observer hears a frequency of \(560\ \text{Hz}\). When the source recedes, the observer hears \(460\ \text{Hz}\). Determine (i) the actual frequency emitted by the source and (ii) the speed of the source in \(\text{m s}^{-1}\).
