## 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.
- lambda = v / f
- lambda = 343 / 440
- lambda = 0.7795 m
- lambda = 77.95 cm
