The same as the red spectrum, an electromagnetic wave with a different frequency.
black because as it absourbs light true black is invisable to the human eye.
Sunburn has been around for many centuries.
Red , Yellow and Blue are the Primary Colours because you cannot make them from other colour pigments. Also Red colour is at the Long wave end of the Spectrum. Blue colour is at the Short wave end of the spectrum. Yellow colour is at the Mid-point of the spectrum. When mixed;- Red & Blue = Purple Red & Yellow = Orange Blue & Yellow = Green
The light spectrum can be viewed as a slinky. When compressed, the light waves change to the blue end of the spectrum. When stretched, the the light changes to the red end of the spectrum. Physicists know that our universe is expanding because galaxies further away change to the red end of the spectrum. This means the galaxies were once closer together in the past than what they are now. This is one of the many pieces of evidence that supports the Big Bang Theory.
nice question! actually when a wave approaches an observer the wave length of the wave decrease and as it move far from us its wavelength increase. it is quiet difficult to understand so use your imagination. as the wavelenght increase the spectrum will be shifted toward red spectrum and thus called red shift. when Edward Hubble studies spectrum of different star he noticed that because of some color spectrum were missing, other spectrum got shifted to ward red. it it moved toward red then that mean that wavelength was increasing and if wavelength increases then that means light moves away from us and thus he concluded that each and every star and galaxy was moving away from each other
radio waves
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
The ultraviolet spectrum is 'beyond' (ultra) the violet part of the visible spectrum, that is, beyond the short end of the wavelength range. The infrared spectrum is 'within' (infra) the long end of the wavelength range. The two terms have nothing to do with color, which defines the visible spectrum between violet and red.
A purely scientific answer is that there are no more colours beyond what you see in a rainbow. The rainbow constitutes the visible spectrum, meaning that it is the only part of the electromagnetic spectrum that is visible to the human eye as light. Beyond the red 'end' of the spectrum is Infra Red Radiation and beyond the violet 'end' is Ultra-Violet and beyond that X-rays. There is a Wikipedia article about the electromagnetic spectrum here: http://en.wikipedia.org/wiki/Electromagnetic_spectrum

Red light has the longest wavelength in the visible spectrum.
The color of an electromagnetic light wave is determined by its wavelength. Shorter wavelengths correspond to colors towards the blue end of the spectrum, while longer wavelengths correspond to colors towards the red end of the spectrum.
No, they are a more energetic type of electromagnetic radiation found beyond the blue end of the visible spectrum. Infrared rays are also electromagnetic but have much less energy and longer wavelengths and are found beyond the red end of the visible spectrum.
violet with shortest wave length is deviated most this type of spectrum ranging from violet and one end red at other and without any discontinuous is called continuous spectrum
The frequency of the wave determines the color of light. Higher frequency waves correspond to colors towards the blue end of the spectrum, while lower frequency waves correspond to colors towards the red end of the spectrum.
The longest visible wavelengths are thoseat the red end of the spectrum (rainbow).
The visible light with the longest wavelength is the last coloryou can see on the red end of the spectrum.
