A source of sound is moving along a circular orbit of radius 3 m with an angular velocity of 10 rad/s. A sound detector located far away from the source is executing linear simple harmonic motion along the line BD with an amplitude\[BC=CD=6\text{ }m\]. The frequency of oscillation of the detector is \[5/\pi \] per second. The source is at the point A when the detector is at the point B. If the source emits a continuous sound wave of frequency 340 Hz, find the minimum frequencies (in Hz) recorded by the detector.
