any light is electromagnetic radiation that is perceived by the eye.According to various physical theories, it may be considered as a wave and the photon flux - depending on the situation.Subjective characteristics of light is the color that is perceived by the human eye.For monochromatic radiation is determined by the frequency of the wave it, and for the complex - the spectral composition.
general concept
Monochromatic light - a light oscillation waves which have the same frequency.It can be attributed both to the eye of the spectrum and invisible (infrared, X-ray, ultraviolet).
Under monochromatic understand the emission of electromagnetic waves, which are the same length and frequency of oscillation.As you can see, these two definitions are identical.It can be concluded that the light is monochromatic and monochromatic radiation - is the same.
Obtaining a light tone.Monochromators
Under natural conditions, there is no source that would emit light with a wavelength and the same oscillation frequency.Monochromatic light was obtained by means of special devices, which are called monochromators.This is possible in various ways.For the first option used prismatic system.With their help allocate flow with the necessary degree of monochromaticity.
second method, which allows to select the monochromatic light beam, based on the properties and use of the diffraction grating.A third way to obtain a production of discharge lamps or light sources that during the emission wave is only one electronic transition.
The use of monochromatic light and its radiation devices
The simplest example is the laser.Its creation was made possible by the discrete properties of light.Using laser beams different versatility: they are used in medicine, advertising, construction, industry, astronomy and many other areas.When the wavelength of monochromatic light emitted by the device, owing to its design can be strictly constant.By the time it can be both continuous and discrete light.Monochromators also include various types of spectrometers, which are used in various fields.
monochromatic light and its effects on the human body
basic spectral colors are red, orange, yellow, green, blue, indigo, violet.There is a branch of medicine that studies the impact on the human body.It's called oftalmohromoterapiey.
use of red light helps in getting rid of various diseases of the upper respiratory tract.Orange helps to improve blood circulation and digestion, accelerates regeneration of muscle and nerve tissue.Yellow beneficial effect on the gastrointestinal tract and has a cleaning effect on the whole body.
Green cures hypertension, neurosis, fatigue, insomnia.Blue because of its antibacterial properties able to remove the inflammatory processes in the throat.Also it is used in the treatment of rheumatism, eczema, vitiligo, purulent lesions on the skin.Blue monochromatic light has beneficial effects on the parasympathetic nervous system and the pituitary gland, and purple improves muscle tone, brain, eyes, helps to normalize the work of the digestive tract and nervous system in general.
As can be seen from the above, monochromatic light is needed not only for the idealized experimental physicist, he is able to bring real benefits to health, not to mention the industry and other spheres of human activity.
