A violin string tuned to 485.0 Hz is found to exhibit 2.0 beats per second with a guitar string. The guitar string is then tightened, and the beat frequency is found to increase. What was the original frequency of the guitar string?
2 beats per second means that it’s a 2Hz different. Since the frequency of the beats INcreases when the string is tightened, that means that the string is already vibrating faster than the violin string.
