波长计算器 — 公式

Wavelength

Wavelength is the spatial distance between two consecutive points of equal phase on a wave.

Formula

lambda = v / f

Longer wavelengths correspond to lower frequencies when speed is constant.

计算示例

Concert A note (440 Hz) in air at 343 m/s.

  1. lambda = v / f
  2. lambda = 343 / 440
  3. lambda = 0.7795 m
  4. lambda = 77.95 cm
