Electromagnetic Waves From Highest To Lowest - News
Even though evidence that children are more sensitive to nonionizing radio waves than adults is lacking, "there is genuine concern for the obvious reasons that children are young, growing, and have many years of life remaining," the authors of an
About half the nation's airport scanners rely on electromagnetic waves to create the images with what's known as millimeter wave technology. The rest of the scanners use X-ray beams in what's known as backscatter technology.

The table used by researchers to classify, examine and explain the various forms of electromagnetic radiation are called the electromagnetic spectrum. Electromagnetic waves can travel through space, although the sound waves require a medium through. The majority of radiation is not harmful, although more concentrated radiation such as UV, X-rays and gamma rays can be particularly dangerous. Scientists studying the electromagnetic theory with respect to our world to ensure that radiation from computers, cell phones, and power transmission lines will not harm us.
The electromagnetic spectrum contains seven basic types of radiation. Highest to lowest, are gamma rays, X rays, ultraviolet, visible, infrared, microwaves and radio waves. Radio waves have the longest wavelength, they can be as long as a football field. Electromagnetic waves are invisible to the human eye, but they transmit signals from television, cell phones, radio and wireless internet. Radio waves are emitted by stars and gas in space.Microwaves can not be seen and have a wavelength slightly shorter, they send sound through the phones, make them work for Doppler weather radars and filter through space as a light background. When we talk about the Big Bang theory or the study of the Milky Way Astronomers often refer to the microwave.
A relatively small amount of radiation is contained in a wave infrared, which is the third longest wavelengths of the electromagnetic spectrum. The heat of the sun is infrared in nature. Infrared is an electromagnetic pulse used by snakes to hunt warm-blooded animals, in the dark.We use infrared sensors to military tactics, hunting, and even to understand the bootleggers who illegally copy movies in theaters. Dust between the stars is illuminated by infrared waves.
After the radio, microwave and infrared radiation, "invisible radiation" refers to what we can see the electromagnetic spectrum. Types of electromagnetic fields for visible light are the sun, reflected light, fireflies, light bulbs, rainbows, stars and fast-moving particles. When we get sun burned, we see the effects of ultraviolet rays, although we can not really see them.Carcinogenic rays are generally protected by our ozone layer. Damage can occur from holes in the ozone layer or prolonged exposure. UV rays are also emitted by stars and other objects are extremely hot.
Why is our life so dependent on the electromagnetic spectrum? Aside from adding a few of the most significant technologies of our time, the earth gets its energy from the sun, driven by light, which maintains a prosperous existence. Rather than being nothing more than the uninhabitable frozen rock like many other planets, our earth photosynthesis, water cycle and atmosphere.These electromagnetic waves deserve our thanks on many levels.
