All electromagnetic radiation, such as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays, travel at light speeds. They are all produced by swinging magnetic or electric fields. Thus, all these different wavelengths are connected to matter by pulling, pulling, and scattering. Electromagnetic spectrum is a continuous wavelength that varies from several miles to an inch.
Infrared technology – uses
Infrared technology, from electromagnetic radiation, are man-made imaging technologies. In general, it is important in many ways. For example, there are infrared vision glasses that can be used at night to identify other people and other hot objects. These were originally built by the military, but they are also getting many other uses.
An infrared-type imaging system can be used to photograph homes at night and to search for hot and cold places. In those places, the heat flows from the house, so one can see how well the cover works. There are also many non-military applications for satellite infrared imaging.
For example, they can be used to monitor forest fires and control plant pollution. Infrared satellites are now being used to control volcanoes. When a volcano erupts, the top of the volcano begins to heat up a little as the tropics close to the surface, and one can determine whether or not a volcano will erupt.

Visible light – the amount of light that people can see
The visible light shines almost in the center of the electromagnetic cell. It covers a very narrow region, only four to seven hundred billion meters. It is defined as the wavelength that the eyes can detect, and that is about the region.
There is nothing different in this region than the physics, but that is why the eyes are so important in this narrow region. The visible light beams are further divided into colors, and those wavelengths are smaller. The colors of the visual string are not equal in width, red and green are very wide, but yellow is very narrow. It is only 570 to 590 billion meters, a very narrow region.
Visual Light Study by Isaac Newton
Isaac Newton had a very interesting show in 1665 and 1666. He studied the nature of the colors and realized that when all the colors of the rainbow are combined, they produce white light. He used prism to decompose white light into colors, and then used the second prism to regenerate those colors into white light.
It is said that the eyes have three different colors called cones. These distinguish red, green, and blue, and when a person combines red, green, and blue together, they see the color as white. Realizing this, Newton invented the Newton color wheel.

Ultraviolet, intense electromagnetic spectrum radiation
Ultraviolet radiation reaches tens and four billion billion meters at high and high frequencies, high and high intensities. The energy of ultraviolet radiation is comparable to the energy that binds atoms together, which is why ultraviolet radiation can disrupt the skin’s elasticity. It can destroy molecules and therefore kill cells.
Ultraviolet radiation itself is usually divided into three wavelengths. The longest ultraviolet wavelength is called near UV. That is 300 to 400 billion square meters, and it is mainly absorbed by the skin. It causes chemical reactions called skin rejuvenation and the production of much-needed vitamin D.
Then there are 200 to 300 billion meters of radiation. That is called ultraviolet light, which penetrates deep into the skin and can kill cells. And finally, there is radiation even for short wavelengths. That is called ultraviolet light, and that radiation is carried by air, so it does not descend to the surface of the earth.

Sunscreen – The best solution against UV rays
The short-range ultraviolet rays in the atmosphere are harmful, and sunburn can block these harmful rays. Solar closures are rated. The number indicates if there is a specific exposure without sun protection within an hour.
Sunscreen is a wonderful chemical. For chemists to develop a sunscreen, the method was to find a substance that could be applied in a very thin, transparent coating. And then people had to be a non-swim layer because people swim. It should also be clear of visible light and ultraviolet light.
Fluorescence – Amazing use of ultraviolet rays
There is one use of ultraviolet light called “black light” or fluorescent. The amazing fluorescent display of DayGlo materials is one example in everyday life. This ultraviolet radiation hits an object, and then only shines brightly in daylight.
In broad daylight, two phrases that seem boring are yellow or gray. However, consider switching off the lights using ultraviolet light. When ultraviolet light is applied to these materials, the materials capture the ultraviolet and then emit some of that energy as visible light, and that is a fluorescent phenomenon. So, here it will be a wonderful fluorescent rock and an invisible color used to send boring, gray rock, gray powder messages.
Common questions about electromagnetic spectrum radiation
They are infrared, visible light, and ultraviolet rays Electromagnetic spectrum rays. In modern technology, each has its own characteristics and uses.
One Electromagnetic spectrum raysInfrared radiation is used in a variety of ways today. One of the uses is to identify any leaks in energy. This radiation helps to track forest fires, volcanoes, and pollution.
UV is one of the closest Electromagnetic spectrum rays It is absorbed by the skin, which produces vitamin D, which is essential for the body. It also causes certain chemical changes (skin) near ultraviolet light.
