Neco Model Questions Vol1 2024 Physics Question 50
Practice objective / multiple choice question 50 from the 2024 Neco Model Questions Vol1 Physics examination.
A source emits sound of frequency \(f=500\) Hz and moves towards a stationary observer with speed \(v_{s}=30\) m s⁻¹. The speed of sound in still air is \(c=340\) m s⁻¹, and a wind blows from the source toward the observer at \(v_{w}=10\) m s⁻¹.\\ (a) What frequency does the observer hear?\\ (b) If the observer now walks away from the source at \(v_{o}=20\) m s⁻¹ (still with the same wind), what frequency is heard?
