Igcse Model Questions Vol1 2021 Physics Question 6
Practice objective / multiple choice question 6 from the 2021 Igcse Model Questions Vol1 Physics examination.
A siren emits a sound of frequency \(500\ \text{Hz}\). The speed of sound in air is \(340\ \text{m s}^{-1}\). An observer hears a frequency of \(531\ \text{Hz}\) as the source approaches and \(472\ \text{Hz}\) as it recedes. Assuming the observer is stationary, calculate the speed of the siren (in \(\text{m s}^{-1}\)), giving your answer to two significant figures.
