λ = v / f

Where:

* λ (lambda) represents the wavelength

* v represents the speed of the wave (e.g., the speed of light for electromagnetic waves)

* f represents the frequency of the wave

Explanation:

* Wavelength is the distance between two successive crests or troughs of a wave.

* Speed is the distance traveled by the wave per unit of time.

* Frequency is the number of waves that pass a given point in one second.

Therefore, the equation states that the wavelength of a wave is directly proportional to its speed and inversely proportional to its frequency.
