The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.[1] The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.
The electromagnetic spectrum extends from low frequencies used for modern radio to gamma radiation at the short-wavelength end, covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. The long wavelength limit is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length, although in principle the spectrum is infinite and continuous.

What is a spectrum notation of color?
spectrum
Which of these statements about the EM spectrum is false?
Most of the EM spectrum is visible light.
Continuous spectrum with dark lines where light is absorbed?
dark-line spectrum...
What is another name often used for spectrum?
The visible light portion of the electromagnetic spectrum.
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
What are some examples of microwave on the elctromagnetic spectrum?
microwaves is one
What determines where electromagnetic waves fall on the elctromagnetic spectrum?
Frequency determines this.
Why is light called elctromagnetic radiation?
because it resides in the electromagnetic spectrum which is the measure of light.
What is the elctromagnetic background?
The constant noise in the electromagnetic spectrum, caused by various sources, from lightning on Jupiter to someone using an electric razor. There is electromagnetic energy present across the frequency spectrum, which is called 'noise' because it carries no intelligence that we can discern.
What percent of elctromagnetic is visble light?
Less than 1 %
What is the scientific tool based on how atoms absorb and emit elctromagnetic radiation?
spectroscopy
Who was the first person who proved visible light is only part of the elctromagnetic spectrum?
While I wasn't able to find a specific name associated with the unification of the electromagnetic spectrum, I would suspect that it was James Clerk Maxwell, the man who discovered the link between electricity and magnetism, thus coining the term "electro-magnetic". The spectrum itself is just a list of the ranges of energy that a photon can be at. By studying visible light we can develop the equations that eventually lead to everything from radio waves to gamma waves.
What is elctromagnetic energy?
Energy that is radiated in a wave such as radio waves, white light, uv light and xray.
What do stars do?
A star generates light and heat by nuclear fusion and radiates it away via elctromagnetic radiation.
What do you mean by long term spectrum?
bacause the spectrum means spectrum so the spectrum is known as spectrum is called as spectrum
The energy produced by elctromagnetic waves?
Electromagnetic waves carry energy from place to place, but they don't produce it. You have to produce the energy that you want them to carry.
What is main difference between prism spectrum and grating spectrum?
Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray
