Answer: the wavelength is 0.795 m
Explanation: The speed, frequency, and wavelength of note are related in the next equation:
λ = v/f
where λ is the wavelength, f is frequency and v is velocity.
Now, we know f = 440hz or 440*1/s and v = 350m/s, we can replace it in the equation and find λ
λ = (350m/s)/(440/s) = 0.795 m
The value of the wavelength of the musical note A above middle C is 0.795 meters.
Wavelength is the distance between two points of the two consecutive waves. It can be given as,
[tex]\lambda=\dfrac{v}{f}[/tex]
Here (v) is the speed of wave and (f) is the frequency of the wave.
The musical note A above middle C has a frequency of 440 Hz and the speed of the sound is known to be 350 m/s.
As the value of frequency of the note is 440 Hz and the speed of the sound wave is 350 m/s.
Thus the wavelength of this wave can be find out using the above formula as,
[tex]\lambda=\dfrac{350}{440}\\\lambda=0.795\rm \; m[/tex]
Hence, the value of the wavelength of the musical note A above middle C is 0.795 meters.
