Igcse Model Questions Vol1 2023 Physics Question 32
Practice objective / multiple choice question 32 from the 2023 Igcse Model Questions Vol1 Physics examination.
A train sounding a horn emits a frequency of \(f_{0}\) Hz in the rest frame. When the train approaches a stationary observer, the observer hears a frequency of \(960\ \text{Hz}\). After the train passes and recedes, the observer hears \(720\ \text{Hz}\). The speed of sound in air is \(340\ \text{m s}^{-1}\). Determine (a) the speed of the train in \(\text{m s}^{-1}\) and (b) the original emitted frequency \(f_{0}\) in hertz.
