Physics problem string tension

  • #1
Two strings are adjusted to vibrate at 260 Hz. One string is tightened then 3 beats per second is head when the string vibrate at the same time. What is the new frequency of the tightened string.
I am using Fbeat=F1-F2; so wouldn't the answer just be 263 Hz

Well, can you explain why 263 Hz, and not 257 Hz?

The tension increased so the frequency must be greater than the F1. But when F2 is isolated the result would be 260-3 = 257hz
