Question

The tine of a tuning fork, when struck, has an amplitude of 0.13 cm. If the frequency of the fork is 200 Hz, what total distance will the tine travel in 1.0 minute?

Answer 1

Tuning fork has frequancy f= 200 Hz +> it makes 200 oscollations during 1 s.
Since 1 min=60 s, it makes 200•60=12000 oscillations/min.
Each oscillation = 4A=4•0.13 cm=4•0.0013 m=0.0052 m.
Therefore,
s=0.0052•12000=62.4 m.

Answer 2

where does the 4 come from?

Answer 3

the 4 comes from the amount of times .13 is moved on a transverse wave. It moves up(+.13), moves down to line (+.13), moves down(+.13, )moves back up(.13). = 4*.13
