Wavelength
The wavelength of a wave is the distance it requires to complete one oscillation. In astronomy, we often refer to the wavelength of a given spectral line or other form of electromagnetic radiation (light).
Wavelength is the title of a 1978 album by Van Morrison.

Current Performance of Ground-Based Interferometers
Here is a list of currently existing astronomical interferometers, and some parameters describing their performance.
Wavelength
(a) The distance between adjacent peaks in a wave-train is the wavelength.
(b) A mathematical function describing the behavior of a particle according to quantum mechanics. The wave function satisfies Schrodinger's wave equation.
Wavelength and Frequency
The wavelength is the distance between individual waves (e.g. from one peak to another). The wavelengths of visible light range between 400 to 700 billionths of a meter.

wavelength of maximum intensity: The wavelength at which a perfect radiator emits the maximum amount of energy; depends only on the object's temperature.
wavelength the distance between two crests or two troughs of a wave. weight amount of the force of gravity felt by an object. It is measured in units of newtons. It depends on the strength of the surrounding gravity field.
Wavelength Dependence of Classification Parameters
As shown in the M81 images atop the classification page, some of the quantities we've been decomposing are strong functions of wavelength, particularly bulge/disk ratio.
One wavelength
equals the distance between two successive wave crests or troughs.
Frequency (Hertz)
equals the number of waves that passes a given point per second.

Wavelength
The distance between consecutive crests of a wave. This serves as a unit of measure of electromagnetic radiation.
Wavelength: A wave is an oscillation in space, with peaks and troughs. The distance from one peak to the next is the wavelength. It is measured in units of distance. The wavelength of ocean water waves will be meters.
A wavelength, or frequency, of light that is more energetic than visible light, but less energetic than x-ray radiation. Ultraviolet, or UV, radiation ranges in wavelength between 10^-8 and 10^-7 meters and in frequency between 10^15 and 10^17 Hz.
A wavelength at which radiation is emitted, creating a bright line in the spectrum.

The wavelength or frequency distribution of blackbody radiation was studied in the 1890s by Wilhelm Wien of Germany. It was his idea to use as a good approximation for the ideal blackbody an oven with a small hole.
The wavelengths of visible light range from 400 nm to 700 nm. Infrared and radio waves have longer wavelengths but lower frequencies; ultraviolet and gamma ray have shorter wavelengths and higher frequencies.

Compare the wavelength of a radio wave with that of an x-ray. The wavelength uniquely identifies the type of radiation. Radio waves are between a millimeter and hundreds of kilometers long that's why TV and radio antennas are the size they are.
