A sound detector located far away from the source is executing S.H.M. along the line with an amplitude 1m. The freuency of oscillation of the detector is 5 per sec. 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, the minimum and maximum frequency recorded by the detector (velocity of sound in air = 330 m/s)

The figure shows a snap photograph of a vibrating string at `t = 0`. The particle `P` is observed moving up with velocity `20sqrt(3) cm//s`. The tangent at `P` makes an angle `60^(@)` with x-axis.
