Gce Model Questions Vol1 2017 Physics Question 4
Practice objective / multiple choice question 4 from the 2017 Gce Model Questions Vol1 Physics examination.
A source of sound emits a frequency \(f_0 = 500\ \text{Hz}\) and moves towards a stationary observer with speed \(30\ \text{m s}^{-1}\). The speed of sound in air is \(340\ \text{m s}^{-1}\). A rigid wall is located \(100\ \text{m}\) behind the source. The observer receives both the direct sound and the sound reflected from the wall. Calculate the frequency of the reflected sound heard by the observer.
