givin a beat frequency 4.1 Hz and a tuning fork of 256 Hz what is the frequency of a second tuning fork that has a lower pitch?

Respuesta :

If the two sounds with the given frequency are in resonance, specifically destructive resonance, the frequency of the second tuning fork will be determined by calculating the difference between the two forces. 
                                   second tuning = 256 Hz - 4.2 Hz
        
                                    second tuning = 251.9 Hz
