1. The problem statement, all variables and given/known data To check the frequency of an unknown tuning fork, it is struck with one that vibrates at 256 Hz. While they vibrate together, beats with a period of 2 seconds are heard. What are the two possible frequencies for the unknown fork? 2. Relevant equations f1-f2 = beats 1/T = f 3. The attempt at a solution f1= 256Hz Tb = 2 s f = 1/2s = .5 Hz f1-f2 = .5 Hz f2 = 256.5 or 255.5 Is this correct? I think the wording threw me off.
