here's a link to a picture of the em spectrum along with corresponding wavelengths for each type of radiation:\n\nhttp://kingfish.coastal.edu/marine/Animations/Images/Electromagnetic-Spectrum-2.png

wavelength = speed of light/frequency\n\nwavelength = (299792458[m/s] / 100000000[1/s])\nwavelength = 2.99792458m

They are alll electromagnetic waves.  They all have different frequencies.  Radio waves have the lowest and gamma rays have the highest.

A spectrometer is an optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. The variable measured is most often the light's intensity but could also, for instance, be the polarization state. The independent variable is usually the wavelength of the light, normally expressed as some fraction of a meter, but sometimes expressed as some unit directly proportional to the photon energy, such as wavenumber or electron volts, which has a reciprocal relationship to wavelength. A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities. Spectrometer is a term that is applied to instruments that operate over a very wide range of wavelengths, from gamma rays and X-rays into the far infrared.

In a transverse wave, the wavelength is the distance between the crests (or troughs) of the wave.\n\nThe frequency is the number of times a wave passes in a certain amount of time.

Sound waves does not fall under Electromagnetic spectrum. Only electromagnetic waves (Eg:- Light, X-ray, Gamma Ray, radio waves, Infrared rays etc) travel through vacuum. \n\nSound waves require vibration in the air molecules. Since there is no atmosphere in the space, sound can't travel.

From the point of view of Physics, an electromagnetic (EM) wave is a self propagating wave in space with electric and magnetic components. It carries energy and momentum which may be imparted when it interacts with matter. EM wave can be predicted by Maxwell's equations. \n\nFurther informations: http://en.wikipedia.org/wiki/Electromagnetic_wave

Electromagnetic radiation is generally described as a self-propagating wave in space with electric and magnetic components. They are forms of radiation on the elctromagnet ic spectrum!! These components oscillate at right angles to each other and to the direction of propagation, and are in phase with each other. Electromagnetic radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. In some technical contexts the entire range is referred to as just 'light'. [1]\n\nEM radiation carries energy and momentum, which may be imparted when it interacts with matter.\n\nElectromagnetic waves of much lower frequency than visible light were first predicted by Maxwell's equations and subsequently discovered by Heinrich Hertz. Maxwell derived a wave form of the electric and magnetic equations, revealing the wavelike nature of electric and magnetic fields and their symmetry. йō ŞрзĈ\n\nAccording to these equations, a time-varying electric field generates a magnetic field and vice versa. Therefore, as an oscillating electric field generates an oscillating magnetic field, the magnetic field in turn generates an oscillating electric field, and so on. These oscillating fields together form an electromagnetic wave.

I'm not really sure what you're asking for, but I'd answer this question using Physics concepts.\n\nOK, we all know that the visible light spectrum lies between the wavelength of 700nm-400nm. (That's 700 nanometer-400nanometer). 700nm is the red part of the spectrum, and 400nm is the violet part of the spectrum.\n\nAccording to your colour spectrum (ROYGBIV), orange light has a larger wavelength than yellow light.

wavelength = speed/freqency \n=> (3 x 10^8)/(10^15)\nSo that is 3 x 10^-7 m\nor 3000 angstrom

visible light has wavelengths from 400 to 700 nm. Frequency is inversely proportional to wavelength. The longer the wavelength (lower frequency), up to 700nm, the closer the color will be to red. As wavelength decreases, the color will shift through orange, yellow, green, blue, to violet at 400 nm. See; the color spectrum (more info in linked wikipedia article)

It depends on the wavelength of the light and its energy.

Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation.\n\nThe term electromagnetic radiation is also used as a synonym for electromagnetic waves in general, even if they are not radiating or travelling in free space. This sense includes, for example, light travelling through an optical fiber, or electrical energy travelling within a coaxial cable.\n\nElectromagnetic (EM) radiation carries energy and momentum which may be imparted when it interacts with matter.

Energy is directly proportional to frequency, as governed by the equation E=hv, where E is energy, h is planck's constant, and v is freuqency, in hertz.  \n\nSince wavelength is inversely proportional to frequency, and energy is directly proportional to wavelength, energy is inversely proportional to wavelength.  \n\nc=(wavelength)(frequency), where c is the speed of light\nE=(h)(v)=(h)(c/wavelength)

Originally a spectrum was what is now called a spectre, i.e., a phantom or apparition.\n\nWhen white light is passed through a prism, colours 'appear' as if from nowhere, so this is where the link comes from

The equation you want to use is \n\nfrequency * wavelength = speed of light\n\nor in order to calculate wavelength\n\nwavelength = speed of light / frequency\nwavelength = (3 x 10^8 m/s) / (100 MHz)\n\nIn the last equation the units don't match so convert in this way:\n100 MHz = 100 x 10^6 Hz = 1 x 10^8 Hz \n\nA Hz is just 1/s so now the units do match.\n\nwavelength = (3 x 10^8 m/s) / (10^8 1/s) = 3 m\n\n3 meters is a radio wave.

if you mean spectroscopy and related fields here's something.\n\nspectrum:  variation of intensity with frequency or wavelength.\n\nstudy of intensity of the radiation.
