The displacement at a point due to two waves are \( y_{1}=4 \sin (500 \pi t) \) and \( y_{2}=2 \sin (506 \pi t) \).
\( \mathrm{P} \) The result due to their superposition will be W
(1) 3 beats per second with intensity relation between maxima and minima equal to 2
(2) 3 beats per second with intensity relation between maxima and minima equal to 9
(3) 6 beats per second with intensity relation between maxima and minima equal to 2
(4) 6 beats per second with intensity relation between maxima and minima equal to 9
