Electromagnetic

Depending on the type of wave, its wavelength can be relatively large or very small. The wavelength of an AM radio wave is about 300 meters (one-fifth of a mile), while the X-rays emitted by a dentist's X-ray machine might have a wavelength of only a nanometer (one billionth of a meter). Scientists divide this enormous range into several sections. From longest waves to shortest, these include radio waves (including AM, FM, and television), microwaves, infrared (sometimes called heat radiation), visible light, ultraviolet, X-rays, and gamma rays (which are smaller than an atom!). A rainbow that we see has different tyoes of colors,but what we dont see is the colors represents just a small part of a much larger "spectrum" of energy, which includes radio waves, X-rays, and many other kinds of energy that we can not see. Over the past century, astronemers have discovered telescopes and other kinds of tools tofive us insights intothe workings of the universe. Just like sound waves and oceans waves light behaves in its own wave as well. It also acts like tiny particles (protons). Also radiotransmissionwaves travel at the same speed as light, and alsohave similar properties. They are both electromagnetic waves. These waves are synchronized ripples ina magnetic field. Eventually, astronomers realized that many other sorts of "waves" and "rays" are also electromagnetic waves, and differ from light and radio only in terms of their wavelength. Depending on the type of wave, its wavelength can be relatively large or very small.

All of these types of electromagnetics are the kind of the same but they're just made under diferent conditions. The ability to see all these different electromagnetic waves has helped astronomy enter a "golden age." As radio telescopes, infrared sensors, and X-ray cameras become more sensitive and more capable, we can expect even more discoveries. By using all the colors of the electromagnetic rainbow, we get a more complete view of the universe.
