The word 'wavelengths' is correct and usable in written English.
You can use it when talking about the distance between crests of electromagnetic waves, which is also known as the wavelength of a wave. For example, "The colors of the visible light spectrum are spread across seven distinct wavelengths."
Different diazo compounds absorb particular wavelengths of light (it is these structures which give dyes their distinctive colour).
Mapping the cosmic microwave background is hard because the Milky Way itself shines quite brightly at these wavelengths, making the background hard to discern.
And it gets better the new camera will need less memory and power, and may be able to capture images at wavelengths that could prove useful for airport security.The trick is to manipulate the way in which the camera captures and stores information.
They have been zipping through the universe ever since.As the cosmos stretched further over subsequent aeons, so have those photons' wavelengths.
Applying that sort of ratio to the SKA, which is designed to work with wavelengths measured in metres, would require a dish thousands of kilometres across.Dishes of the dayBuilding such a dish is obviously impossible.
This allows Dr Koppens and Dr Konstantatos to span all wavelengths from ultraviolet to infra-red, greatly increasing the utility of any photodetector that might emerge.
Lasers, on the other hand, can be tuned to emit only the wavelengths needed.
The NPL's researchers have come up with a way of filtering out other wavelengths of light with a technique that they are, for now, keeping up their sleeve.
Since, optically speaking, energy levels correspond to wavelengths, such an arrangement can be tweaked to reflect some wavelengths and preferentially emit others.
As a consequence, the wavelengths of the chilled atoms become very large (atoms, like everything else, are both particles and waves).
The smaller wavelengths of ultraviolet light allow it to be more closely focused, with the ability to print circuits as thin as 0.03 microns.
