Monochromatic light and radiation

Any light is electromagnetic radiation, which is perceived by the eye. According to various theories of physics, it can be considered as a wave, and a stream of photons - depending on the situation. The subjective characteristic of light is the color that is perceived by the human eye. For monochromatic radiation, it is determined by the frequency of the wave, and for the complex one by the spectral composition.

General concept

Monochromatic light is a light wave oscillation that has the same frequency. To it it is possible to carry as a part of the spectrum perceived by an eye, and invisible (infra-red, x-ray, ultraviolet).

Monochromatic refers to the radiation of electromagnetic waves, which have the same length and frequency of oscillation. As we see, these two definitions are identical. It can be concluded that monochromatic light and monochromatic radiation are one and the same.

Getting a light of one tone. Monochromators

In natural conditions, there is no source that emits light with one wavelength and the same oscillation frequency. Monochromatic light is obtained with the help of special devices called monochromators. This is possible in various ways. Prismatic systems are used for the first variant. With their help, a stream with a necessary degree of monochromaticity is isolated.

The second method, which makes it possible to separate a monochromatic beam of light, is based on diffraction properties and the use of a diffraction grating. The third method of production is the production of gas-discharge lamps or light sources in which only one electronic transition occurs during the emission of a wave.

The use of monochromatic light and its radiation devices

The simplest example is a laser. Its creation was made possible by the discrete properties of light. The use of laser beams is multifaceted: they are used in medicine, advertising, construction, industry, astronomy and many other areas. At the same time, the wavelength of monochromatic light emitted by the instrument, due to its design, can be strictly constant. In time it can be either continuous or discrete light. Monochromators also include various kinds of spectrometers, which are used in a variety of spheres.

Monochromatic light and its effect on the human body

The main spectral colors are red, orange, yellow, green, blue, blue, purple. There is a direction of medicine that studies their effect on the human body. It is called ophthalmic chromotherapy.

The use of red light helps in getting rid of various diseases of the upper respiratory tract. Orange helps improve blood circulation and digestion, accelerates the regeneration of muscle and nerve tissue. Yellow color has a beneficial effect on the work of the gastrointestinal tract and has a cleansing effect on the entire body.

Green contributes to the cure of hypertension, neurosis, fatigue, insomnia. Blue due to its antibacterial properties can remove inflammation in the throat. It is also used in the treatment of rheumatism, eczema, vitiligo, purulent rashes on the skin. Blue monochromatic light has a beneficial effect on the parasympathetic nervous system and the pituitary gland, and purple enhances the tone of the muscles, brain, eyes, and allows the normal functioning of the digestive system and the nervous system in general.

As can be seen from the foregoing, monophonic light is necessary not only for the idealized experiments of physicists, it is capable of bringing real health benefits, not to mention industry and other spheres of human activity.
