Determine, how far off in frequency is the other string. A piano tuner hears one beat every 2.0 s when trying to adjust two strings one of which is sounding 440 Hz.
Answer to Problem 39P
Explanation of Solution
Given:
Frequency ( f ) = 440 Hz.
Time ( t ) = 2 s.
Determine the string length ( l )=?
Formula used:
Beat frequency
Calculation:
Beat period is 2.0 seconds,
The string frequency can be determined by using beat frequency,
Conclusion:
The other string is
