The researchers demonstrated that they could custom design a crystal to double the frequency of light
passing through it.
Among the most intriguing--and perhaps most useful--materials of this sort are those exhibiting nonlinear optical behavior that increases the frequency of light
passing through them.
Because relativistic motion alters the frequency of light
, approaching objects actually would appear more blue (signifying higher frequency) and receding objects more red.
Such waves could shift the frequency of light
coming from pulsars and other astronomical objects, complicating the interpretation of such observations.
Chemists quickly grasped the idea of using a laser to hit the molecule with one frequency of light
, exciting one specific chemical bond in the molecule until it broke, leaving it open to react with another molecule but leaving the other bonds untouched.
They're packed very closely together and roughly absorb at the same frequency of light
, leading to very congested optical spectra.
Brown lenses reduce glare sufficiently well, including absorbing the blue frequency of light
in the sun's rays, which makes your surroundings seem hazy.
To do this, they measured the frequency of light
needed to change an electron's energy in a particular way in a molecule called CH, which is composed of one carbon atom and one hydrogen atom.
The metrologists eventually chose Planck's constant, which describes the relationship between the energy of a photon and the frequency of light
It has been experimentally and astrophysically observed that there is an increase in the frequency of light
(photon) when the source or emitter is further away from the body than the receiver.
Esca emulates natural bioluminescence, replicating the wavelength, intensity and frequency of light
emitted by fish and plankton in salt water.
