Pitch is the sensation of certain frequencies to the ear. High frequency = high pitch, low frequency = low pitch.
f = c(speed of the wave) / λ (wavelength)
1. 343m/s / 0.77955m = 439.99 Hz
This corresponds to pitch A
2. 343m/s / 0.52028m = 659.26 Hz
This corresponds to pitch E
3. 343m/s / 0.65552m = 523.349 Hz
This corresponds to pitch C
4. using f = c / λ
λ = c / f
= 343m/s / 587.33 = 0.583999 m = 0.584 m
