Two sources <strong>of</strong> sound <strong><strong>wave</strong>s</strong> beat at 3 Hz. It is known that<br />
the frequency <strong>of</strong> one source is 610 Hz. <strong>The</strong>refore, the<br />
frequency <strong>of</strong> the other source must be:<br />
a) 604 Hz b) 607 Hz c) 613 Hz d) 616 Hz<br />
e) either b) or c) f) either a) or d)<br />
f beat = f 2 – f 1 , the difference in the two frequencies.<br />
