Two vibrating tuning forks produce waves whose equation is given by y_(1) = 5 sin (240 pi t) and y_(2) = 4 sin (244 pi t) . Compute the number of beats per second .

Two vibrating tuning forks produce waves whose equation is given by y_

1.	Two vibrating tuning forks produce waves whose equation is given by y_(1) = 5 sin (240 pi t) and y_(2) = 4 sin (244 pi t) . Compute the number of beats per second .
Answer» <html><body><p></p>Solution :Given `y_(1) = 5 sin (240 pi t) ` and `y_(2) = 4 sin (<a href="https://interviewquestions.tuteehub.com/tag/244-1827768" style="font-weight:bold;" target="_blank" title="Click to know more about 244">244</a> pi t)` <br/> Comparing with `y = A sin (2 pi f_(1) t)` , we get <br/> `2pi f_(1) = 240 pi <a href="https://interviewquestions.tuteehub.com/tag/implies-1037962" style="font-weight:bold;" target="_blank" title="Click to know more about IMPLIES">IMPLIES</a> f_(1) = 120 Hz` <br/> `2pi f_(2) = 244 pi implies f_(2) = <a href="https://interviewquestions.tuteehub.com/tag/122-271030" style="font-weight:bold;" target="_blank" title="Click to know more about 122">122</a> Hz` <br/> The number of beats <a href="https://interviewquestions.tuteehub.com/tag/produced-592947" style="font-weight:bold;" target="_blank" title="Click to know more about PRODUCED">PRODUCED</a> is `\|f_(1) - f_(2)\| = \|120 - 122\| = \|-2\| = 2 ` beats per sec</body></html>
