Neco 2023 Physics Question 26
Practice objective / multiple choice question 26 from the 2023 Neco Physics examination.
An acoustic source emits a sound of frequency \(500\,\text{Hz}\) and moves directly towards a stationary observer. The wavelength of the sound measured in front of the moving source is \(0.65\,\text{m}\). A second identical source remains stationary and also emits \(500\,\text{Hz}\). Determine the frequency heard by the observer from the moving source. (Speed of sound in air = \(340\,\text{m\,s^{-1}}\).)
