Solution Summary
The solution carefully explains the calculations used to arrive at two answers to the problem.
Solution Preview
Let f denote the unknown frequency of the guitar string.
<br>
<br>Now, the beat frequency is defined as fbeat = |f-fknown| where the bars denote "modulus or absolute value".
<br>
<br>Thus, we have 2 equations:
<br>
<br>5 Hz =|f-440| .......... (i)
<br>Let f denote the unknown frequency of the guitar ...
