In this arlicle lets speak about the section of the electromagnetic spectrum that is visible to the human eye and not to all of the visible people and is invisible to the observer.
About electromagnetic spectrum
Here is some information about the electromagnetic spectrum.
Some relevant colors and wavelengths:
Yellow 591-574 nm
Violet 456-394 nm
Orange 624-596 nm
Red 781-621 nm
Green 578-491 nm
Blue 499-451 nm
These rays, like light, are a form of electromagnetic radiation. They are produced in a cathode ray tube: electrons are emitted from a heated cathode and then accelerated toward the anode.
When electrons hit the anode, they generate energy in the form of X-rays. X-rays were discovered by Rontgen in 1895.
UV-A, between 320 and 400 nm-results in a faster, more unstable tan UV-B between 280-320 nm-the cause of delayed tanning UV-C, between 200 and 280 nm.
Ultraviolet radiation is close to X-rays. Our eyes cannot see this radiation, and our skin does not immediately feel the radiation, which largely explains the risks that can arise during periods of heavy exposure.
Ultraviolet rays also exist in our daily lives as parasites on artificial light sources.
Near infrared is the part of the electromagnetic spectrum immediately after visible light (red). Moderate infrared can usually study the water content of the surface. Far-infrared studies the formation of galaxies and stars.
The uniqueness of the use of microwaves in terrestrial and space telecommunications equipment, as long as their frequency is lower than 12 GHz, they can propagate like light and are not absorbed by the atmosphere.
Conclusion – The section of the electromagnetic spectrum that is visible to the human eye
The eye is sensitive to change in color from red to green or from yellow to red from blue to violet. The eye is made of many layers as you can imagine. These layers are layers of tiny particles which go up and down, forming a complex material in the light. Because these tiny particles cause no interference the light is unaffected by light.
The light passes only through the layers known as wavelengths and is actually reflected back and out. The light coming from the eye goes through one of the few known wavelengths known in nature. Here can be seen the different colors that people see from other people and the ways in which their light can come through the layers of light which is most often, a mixture of different tones of colors. It makes sense then why we are able to see through layers of light.
