# What Is Wavelength?

Wavelength is the distance between identical points in the adjacent cycles of a waveform. It is designated a Greek letter lambda and it is similar to traveling waves and standing waves.

1.
Physics. the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.

2.
on the same wavelength in sympathy or rapport: We seemed to be on the same wavelength from the moment we met.

Wavelength refers to the distance between peaks of electromagnetic radiations. The wave is actually the electromagnetic radiations and the length is the distance between peaks.
Wavelength is the horizontal distance between the crests of two waves. When measuring, the crest is the highest point on each wave. Wavelength is inversely proportional to the frequency of a wave.
