The wavelength (λ) of an EM wave is the distance between two peaks of either electric or magnetic field. The number of cycles per second is called temporal frequency (f).

TEMPORAL FREQUENCY
The term temporal frequency is used to emphasise that the frequency is characterised by the number of occurrences of a repeating event per unit time, and not unit distance. ... Wind-generated waves are described in terms of their period rather than frequency.
