Apiano tuner is using a 392 hz tuning fork to tune the wire for a g-natural note. she hears 4 beats per second. what are the two possible frequencies the piano wire is vibrating at?

A beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. Frequency beat is equal to,

The reference frequency in our case would be 392Hz, and since there is the possibility of the upper and lower range for the amount of beats per second that the two possible frequencies are heard would be

Therefore the two possible frequencies the piano wire is vibrating at, would be 396Hz and 388Hz

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

close lines strong magnet less close weaker
