Figure shows a source of sound moving along the X-axis at a speed of `22 m s^-1` continuously emitting a sound of frequency 2.0 kHz which travels in air at a speed of `330 in s^-1`. A listener Q stands on the Y-axis at a distance of 330 m from the origin. At t = 0, the source crosses the origin P. (a) When does the sound emitted from the source at P reach the listener Q 9 (b) What will be the frequency heard by the listener at. this instant 9 (c) Where will the source be at this instant ?
