Question
A source of sound is moving along a circular orbit of radius 3m with and angular vel of 10rad/d. A sound detector located far away from the source is executing linear simple harmonic motion along the line BD with an amplitude BC=CD=6m. The frequency of oscillation of detector is 5/pi per sec . The source is at point A when the detector is at pt. B. If the source emits continuous sound wave of frequency 340Hz , find the maximum and the minimum frequency recorded by the detector (speed of sound is 340m/s)
