The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.
The electromagnetic spectrum extends from below the low frequencies used for modern radio communication to gamma radiation at the short-wavelength (high-frequency) end, thereby covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length. Until the middle of the 20th century it was believed by most physicists that this spectrum was infinite and continuous.
Most parts of the electromagnetic spectrum are used in science for spectroscopic and other probing interactions, as ways to study and characterize matter. In addition, radiation from various parts of the spectrum has found many other uses for communications and manufacturing (see electromagnetic radiation for more applications).
Contrary to prevailing scientific opinion, Newton felt colours were already present in White light and it was not impurities found in the Prism that gave the Rainbow effect. Subscribe to Earth Science: http://bit.ly/SubscribeToEarthLab
What set Newton apart from other scientists was that he famously devised and performed an experiment to test his hypothesis.

What is Light? Maxwell and the Electromagnetic Spectrum
Up until a couple centuries ago, we had no idea what light is. It seems like magic, no? But there is no magic in this world, really. Just stuff we don't understand. So let's understand light a little better right now, through James Clerk Maxwell and the electromagnetic spectrum.

Light waves, visible and invisible
Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Here is a closer look at the waves we can't see.

Light: Crash Course Astronomy #24
In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s temperature, density, spin, motion, and chemical composition.

Dispersion of Light
Dispersion of Light and Spectrum are discussed in this Colorful video! Is White Light really white in color? How is a Rainbow formed? These are discussed in the video along with exciting experiments on Light. We look at Dispersion of Light through a glass Prism and how the VIBGYOR Spectrum is formed.

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.
The electromagnetic spectrum extends from below the low frequencies used for modern radio communication to gamma radiation at the short-wavelength (high-frequency) end, thereby covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length. Until the middle of the 20th century it was believed by most physicists that this spectrum was infinite and continuous.
Most parts of the electromagnetic spectrum are used in science for spectroscopic and other probing interactions, as ways to study and characterize matter. In addition, radiation from various parts of the spectrum has found many other uses for communications and manufacturing (see electromagnetic radiation for more applications).
No more tears, no more pain, no more crying in the rain No more sorrow, no more blame, in the kingdom of light No more fear, no more lies, no temptation, open eyes Finally found my piece of mind on the road to paradise The revelation of the word is rocking the ages Bringing solution to the world, the fire is raging on Another time, another place, and we'll be standing face to face Life will be an open page, in the kingdom of the light No more night, no more day, everything has passed away Got to find the narrow way that leads to paradise The revelation of the word is rocking the ages Bringing solution to the world, the fire is raging Woe to the nations and kings of the earth When heaven comes down for the final re-birth Taking our place with the Ancient of Days Ruling the kingdom of light The kingdom of light! Woe to the nations and kings of the earth When heaven comes down for the final re-birth Taking our place with the Ancient of Days Ruling the kingdom of light Woe to the nations and kings of the earth When heaven comes down for the final re-birth Taking our place with the Ancient of Days Ruling the kingdom of light
