š1 and š2 are two identical sound sources of frequency 656 Hz. The source š1 is located at š and š2 moves anti-clockwise with a uniform speed of 4 ms-1 on a circular path around š, as shown in the figure. There are three points š, š and š
on this path such that š and š
are diametrically opposite while š is equidistant from them. A sound detector is placed at point š. The source š1 can move along the direction šš. [Given: The speed of sound in air is 324 ms-1].
Consider both sources emitting sound. When š2 is at š and š1 approaches the detector with a speed 4 m sā1 , the beat frequency measured by the detector is _______Hz
