Gce Model Questions Vol1 2024 Physics Question 16
Practice objective / multiple choice question 16 from the 2024 Gce Model Questions Vol1 Physics examination.
Two loudspeakers, A and B, are placed 30 m apart on a straight line. A listener walks along the line from A towards B at a speed of \(5\;\text{m\,s}^{-1}\). Speaker A is stationary, while speaker B is also stationary. The listener hears a beat frequency of \(4\;\text{Hz}\) between the sounds from the two speakers. The speed of sound in air is \(340\;\text{m\,s}^{-1}\) and the average of the two original frequencies emitted by the speakers is \(500\;\text{Hz}\). Determine the difference between the original frequencies of the two speakers (in hertz, to one decimal place).
