The musical note a above middle c has a frequency of 440 hz. if the speed of the sound is known to be 350 m/s, what is the wavelength of this note?

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,

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,

Hence, the value of the wavelength of the musical note A above middle C is 0.795 meters.

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

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
