Wavelength: 77.95 cm at 440.0 Hz

  • At 440.0 Hz in a medium where sound travels at 343.0 m/s, each wave cycle spans 77.95 cm.
  • One wave cycle completes in 2.273 ms (the period T = 1/f).
  • The wavelength (78 cm) is roughly the length of a guitar or a school ruler.
  • Mid-range - most sensitive region for humans (250-2 000 Hz)

Next stepTo change the result, adjust the frequency or switch to a denser medium: wavelength grows as speed increases and shrinks as frequency rises.
