Igcse Model Questions Vol1 2024 Physics Question 32
Practice objective / multiple choice question 32 from the 2024 Igcse Model Questions Vol1 Physics examination.
A source emits sound of frequency \(600\ \text{Hz}\) and moves directly towards a stationary observer with a speed of \(30\ \text{m s}^{-1}\). The speed of sound in air is \(330\ \text{m s}^{-1}\). The observer hears the sound for \(5\ \text{s}\) while the source approaches, then for another \(5\ \text{s}\) after the source has passed and continues moving away at the same speed. How many wave crests does the observer hear in total during the whole \(10\ \text{s}\) interval?
