They found a strong relationship between the outgoing long wavelength radiation (infrared energy) and temperature; however, this relationship varies substantially across the planet.
The proteins and DNA within us cannot be seen even with the best light microscopes since they are far smaller than the wavelength of light.
But after a few weeks I began to meet people who were actually on my wavelength , and who soon became the people I sat with in lectures and met up with outside class.
The deal is not yet quite set in stone – the 42-year-old Bjorkman will join Murray for a week's trial only when he is finished with his commitment on Let's Dance, Swedish TV's version of Strictly Come Dancing – but it's already clear the two are on the same wavelength.
Ordinary light microscopes cannot, however, resolve objects smaller than about 200 nanometres (nm, or millionths of a millimetre), or approximately half the wavelength of visible red light, so anything of this size or smaller appears blurred.
The most general form of the basic wave equation, appearing everywhere from classical mechanics through electromagnetism to quantum physics, is this: x = A × cos (ω × t + d / λ) where λ is the wavelength (the distance between one peak of the wave and the next) and d is the distance along the wave.
In order for this trick to work, though, the distance between the antennae has to be smaller than the wavelength of the light being focused.
This material preferentially absorbs, and is thus heated and expanded by, infra-red radiation with a wavelength of three microns (millionths of a metre).
If the signature of an element is found at a wavelength that is slightly to the blue side of what experiments in a laboratory show, this means the star is moving towards the earth, making the wavelength of the light it was emitting slightly shorter.
When struck by light of the right wavelength , a marked cell will thus fluoresce.To make that happen, the treated cells are spread on a glass slide and scanned with a laser of the correct wavelength.
Next year, the International Committee on Weights and Measures will discuss whether to tie it to something called Planck's constant, a number in quantum mechanics that relates the energy level of a photon to its wavelength.

The term "wavelength" functions primarily as a noun , representing a measurable property of waves. Ludwig examples show its use in scientific and technical contexts. As Ludwig AI confirms, the term is correct and usable in written English.
