Question
12. Using the velocity of sound at 343 m/s and given the frequencies of a piano scale. compute the wavelengths of that scale.
Note: Frequency wavelength note freq wavelength
C4 261.6 G4 392
D4 293.6 A4 440
E4 329.6 B4 493.9
F4 349.2 C5 523.2
13. Wht is the relationship of the frequencies of notes C4 and C5?
14. what is the relationship of the wavelengths of notes C4 and C5?
15. what happened to the wavelength as frequency increased between notes C4 and C5?
Explanation / Answer
the relation between frequency and wav elength is f = v / = v /f where f is frequency v is speed of sound is wavelength Note Frequency Wave length | Note frequency wavelength | C4 261.6 343/261.6 | G4 392 0.875 m = 1.3116m | D4 293.6 1.168 m | A4 440 0.7795m E4 329.6 1.040 m | B4 493.9 0.6944 m F4 349.2 0.9822m | C5 523.2 0.655 m 13. Two notes with fundamental frequencies in a ratio of any power of two (e.g. half, twice, or four times) are perceived as very similar. Because of that, all notes with these kinds of relations can be grouped under the same pitch classRelated Questions
