Wavelength
The measurement of the distance from crest to crest, or trough to trough, in transverse waves such as electromagnetic radiation. In all wave motion the shorter the wavelength, the greater the energy carried by the wave. In compressional waves, such as sound waves, it is the measurement of the distance from rarefaction to rarefaction, or compression to compression. Wavelength is linked to frequency . The longer the wavelength, in waves propagating with the same velocity, the less the frequency. [velocity = wavelength x frequency].
The distance between adjacent peaks (or adjacent troughs) on a wave . Varying the wavelength of light changes its color; varying the wavelength of sound changes its pitch.
1. All electromagnetic radiation (radio waves, microwaves, ultraviolet light, visible light, etc.) is transmitted in waves, and the wavelength is the distance between successive crests of the waves. In optical networks, you can think of different wavelengths as being different colors of light. 2. The distance between points of corresponding phase of two consecutive cycles of a wave. The wavelength, is related to the propagation velocity, and the frequency.
The distance from crest to crest or trough to trough of an electromagnetic wave (see electromagnetic radiation ) or other wave.
