Monochromatic strength can also affect a person on a wavelength of light color feeling, such as dark orange be felt for brown, and dark yellow green be felt for olive, etc.
"All the events we are depicting are so small they are below the wavelength of light," he said.
Remarkably, the new technique, which the researchers call absorbance modulation, makes it possible to create lines that are only about one-tenth as wide as the wavelength of light used to create them.
In a photonic crystal the elements are about the same size as the wavelength of light-a few hundred nanometres (billionths of a metre).
This paper, on the viewpoint of Lorentz transformation of wavelength of lightwave, derives the frequency equation of Doppler effect of light with tow methods.
This happens because of the so-called Doppler effect, which causes the wavelength of light to be stretched when the light's source is moving away from us.
This tells us that the sample is as thick as the wavelength of light, or several multiples of the wavelength at that point.
A rainbow has shown every color contains only a wavelength of light.
