1) To tune a cello string to 220 Hz, you compare its frequency with a 220-Hz tuning fork. Initially, you hear a beat frequency of 6 Hz. Then you slowly tighten the guitar string, which increases its frequency. As a result, the beat frequency decreases steadily to 2 Hz. What are the initial and final frequencies of the guitar string?
