  Frequency Wavelength Calculator
The relationship between a radio signal's frequency and its wavelength can be found by the industry accepted formula wavelength equals 300 divided by the frequency in megahertz.
Assuming the formula is correct, a frequency of 27185 kHz would be equivalent to a wavelength of 11.035 meters (try it on the calculator but be sure to click on Full Wave...), which we would round to 11 meters.
This is important because the length or height of various types of antennas must often be a fraction (usually one-quarter or one-half) of the wavelength of the signal to be transmitted or received.

Wavelength is the distance between two points of the same phase in consecutive cycles on a periodic wave.

 Wavelength-division multiplexing - Wikipedia, the free encyclopedia
However, since wavelength and frequency are inversely proportional, and since radio and light are both forms of electromagnetic radiation, the two terms are closely analogous.
CWDM and DWDM technology are based on the same concept of using multiple wavelengths of light on a single fibre, but the two technologies differ in the spacing of the wavelengths, number of channels, and the ability to amplify signals in the optical space.
In these systems, the wavelengths used are often widely separated, for example the downstream signal might be at 1310 nm while the upstream signal is at 1550 nm.

 What Wavelength Goes With a Color?
Because the blue wavelengths are shorter in the visible spectrum, they are scattered more efficiently by the molecules in the atmosphere.
At sunrise and sunset, red or orange colors are present because the wavelengths associated with these colors are less efficiently scattered by the atmosphere than the shorter wavelength colors (e.g., blue and purple).
One way is that we can feel energy with these wavelengths such as when we sit in front of a campfire or when we get close to a stove burner.

 The Anatomy of a Wave
In fact, the wavelength of a wave can be measured as the distance from a point on a wave to the corresponding point on the next cycle of the wave.
For a transverse wave, the wavelength is determined by measuring from crest to crest.
In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

On one end of the spectrum are radio waves having wavelengths billions of times longer than those of visible light.

 Wavelength Parallelization
Since the number of wavelength points in a calculation is very large and the CPU time scales linearly with the number of wavelength points, parallelization with respect to the wavelength points can lead to large speedups and to the ability to use very large numbers of nodes available on massively parallel supercomputers.
We have developed a wavelength parallelization based on a toroidal topology that uses the concept of wavelength ``clusters'' to distribute a set of wavelength points (for the solution of the wavelength dependent radiative transfer) onto a different set of nodes, see Fig.
For monotonic velocity fields, the RTE is an initial value problem in wavelength (with the initial condition at the smallest wavelength for expanding atmospheres and at the largest wavelength for contracting atmospheres).

WaveLength would appear to be more of a mainstream game compared to some of Tom Cooper's other works - a plain 'ol space based shootemup.
Many thanks to The Doctor for donating this copy of WaveLength to us, and to Matthew Thompson for donating his copy of Worldscape - which we'll endeavour to have patched up and ready to go as soon as possible.
When I first tried to load WaveLength there was no icon on the iconbar, this I eventually discovered was due to the naming of the application and it's sprite.

 Lightwave - Reconfigurable optical networks: Paving the way for dynamic wavelength routing
In the past, optical wavelengths were converted to the electrical domain, where it is much easier to reconfigure circuits, and then converted back to the optical domain.
To guarantee access to any wavelength, network operators must deploy hardware for each channel in their WDM channel plan at initial installation, a process that adds to the cost and complexity of the node--particularly if the node itself requires only a small number of channels.
A wavelength blocker is inserted in the optical bus to remove dropped channels and allow the reuse of those wavelengths.

 Wavelength Division Multiplexing
Each of N different wavelength lasers is operating at the slower Gbps speeds, but the aggregate system is transmitting at N times the individual laser speed, providing a significant capacity enhancement.
The cross-connect is composed of wavelength demultiplexers for the input stage, wavelength multiplexers for the output stage, and fibers interconnecting the two stages.
The same wavelength could be reused by any of the input ports to access a completely different output port and establish an additional connection.

Wavelength, while hardly an improvement over its predecessor [A Period of Transition], may be more interesting because its best songs are better and its worst songs are far worse than anything on the even-keeled but monotonous A Period of Transition.
The phrase "wavelength," with its long "a" vowel sound, is custom-made for Van's melisma and rife with potential metaphors.
With the hook firmly in place, he constructs the rest of the song around it, sometimes leading the listener to it directly, sometimes circuitously: half the fun lies in waiting for it to arrive.

Wavelength is sometimes represented by the Greek letter lambda.

Wavelength will attempt to open a wave file, and upon determining that the header is somewhat in good order, overwrite the data length entry in the header with the actual data length found to be in the file.
This may or may not match the number that is found in the header, and so wavelength will perform no meaningful operation on a correctly formatted wave file.
It is intended to be used to fix files that report the length wrong in the header.

The main wavelength interval is between 200 and 3400 nm (0.2 and 3.4 µm), with the maximum power input close to 480 nm (0.48 µm), which is in the visible green region.
Specular reflectances within the visible wavelength range vary from as high as 0.99 for a very good mirror to as low as 0.02-0.04 for a very smooth water surface.
For the wavelength conditions we set, the surface is considered rough or diffuse and has irregularities where the surface departs from horizontal, at varying slopes.
