In music the note G above middle C has a frequency of about 392 Hz. If the speed of sound in the air is 340 M/S what is the approximate wavelength of this note?
The speed of sound (v) is equal to the frequency (f) multiplied by the wavelength (λ). Mathematically, this can be expressed as v = f * λ.
In this case, the frequency (f) is 392 Hz and the speed of sound (v) is 340 m/s. We can rearrange the equation to solve for the wavelength (λ):
λ = v/f
Substituting the given values, we have:
λ = 340 m/s / 392 Hz ≈ 0.867 m
Therefore, the approximate wavelength of the note G above middle C is about 0.867 meters.
