Wavelength is the distance between two consecutive peaks (or troughs) of a wave. Together with frequency and wave speed, it describes how waves travel through space. The formula λ = v/f relates all three.
Guide étape par étape
- 1λ = v / f (wavelength = wave speed / frequency)
- 2For electromagnetic waves: v = c = 3 × 10⁸ m/s
- 3Frequency f is in Hz (cycles/second)
- 4Wavelength λ is in metres
