Answer:
f= 440.4 Hz or f= 439.6 Hz
Explanation:
In this exercise we have two waves with slightly different frequencies, the A4 chord with f = 440 Hz and the beating with the central chord fbeats = 0.40 Hz, let's use the relation
f_{beat} = | f - f₀ |
f = fo + - f _{beat}
f = 440 + 0.4 = 440.4 Hz
f = 440-0.4 = 439.6 Hz
