How do i find the wavelength of a wave?Wavelength is an important parameter of waves and is the distance between two like points on the wave. The wavelength is calculated from the wave speed and frequency by λ = wave speed/frequency, or **λ = v / f**.

To get the wavelength of a wave simply divide the wavespeed with its frequency.

- Wavelength = λ = Length between wave crests (or troughs)
- Wave Number = κ = 2π/λ (units of 1/length)
- Wave Period = T = Time it takes a wave crest to travel one.
- Angular Frequency = ω = 2π/T (units of 1/time)
- Wave Speed = C = ω/κ Distance a wave crest travels per unit.
- Wave Height = 2a = Twice the wave amplitude.

The wavelength can always be determined by **measuring the distance between any two corresponding points on adjacent waves**. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.
