What is the set of frequencies of the electromagnetic waves emitted by the atoms of an element?
Wavelength is just a length so you can have wavelengths of any length. Gamma rays are the shortest and are typically .00000000001 meters long (or 10^-12 m). Visible light is around .000001 meters (or 10^-6 m) long. Radio waves range from meters to many kilometers.
Frequency is related inversely to wavelength. You can think of yourself standing on a pier and watching the waves go by. The smaller the waves the higher the frequency of their passing and longer waves would go by at a lower frequency.
All EM waves go at the speed of light and their frequency and wavelengths are related by the following equation:
L = c / f
where L (typically written with the greek letter Lambda) is wavelength, c is the speed of light and f is the frequency in Hertz.

What are Frequencies of light emitted by an element called?
"Spectrogram" is a word used to describe the set of specific characteristic frequencies of light which are emitted by a given chemical element when it is sufficiently excited by heat or by some other means.Alternatively, a scientific technique known as "spectroscopy" can be used to identify the elements in some matter of unknown composition and also the emission spectra of molecules can be used in chemical analysis of substances.Because each element's emission spectrum is unique, the "emission spectrum" of a chemical element or chemical compound can be used to help identify what it is. The "emission spectrum" is the name given to the relative intensity of each frequency of electromagnetic radiation http://www.answers.com/topic/emission-spectrum by the element's atoms or a compound's molecules when they are returned to a ground state.
Why do you think are there different color emitted?
There different colors emitted
Why does an element give off light of a particular color?
The simple answer is that when the outer electrons in an atom change their energy state they can only do so in discrete amounts. When they do this a photon is emitted. The photon has a wavelength corresponding to the energy that it carries. We see colour because of this wave length. The electrons in any different atoms are always in different quantum states. All electrons in smiler atoms have the same series of energy levels and so emit the characteristic wave spectrum for that atom. This is the basis of spectrometry.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
Which element is alkaline earth element with the least massive atoms?
Beryllium is the alkaline earth element with the least massive atoms.

What was The quantum theory of energy levels within atoms was aided by?
The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.
Working principle of atomic emission spectroscopy?
Atomic emission spectroscopy works by exciting atoms in a sample to higher energy levels using a flame or electrical discharge. When the atoms return to their ground state, they emit characteristic wavelengths of light. By analyzing the emitted light, the elemental composition of the sample can be determined.
What is a high energy ray emitted from some radioactive atoms that is not affected by a magnetic field?
A high energy ray emitted from some radioactive atoms that is not affected by a magnetic field is called a gamma ray. Gamma rays are a form of electromagnetic radiation with the highest frequency and energy in the electromagnetic spectrum. They are often produced during radioactive decay processes and can penetrate materials easily.
Characteristic series of frequencies of electromagnetic radiation substances emit?
Each substance emits a unique characteristic series of frequencies of electromagnetic radiation when it is heated or excited. These frequencies correspond to specific energy transitions within the atoms or molecules of the substance. By studying these emission spectra, scientists can identify the composition of the substance and gain insights into its structure and properties.
According to the bohr model atoms adsorb electromagnetic radiation with frequencies that correspond to which of the following?
The answer is (The energy necessary to move an electron from one orbit to another)
How is an emission spectrum of an element generated?
All hot solids or dense enough gases emit black body radiation. Gases that are not very dense are are cold absorb particular wavelengths while gases that are not dense but are hot produce their characteristic emission spectrum.
Why do you think are there different color emitted?
There different colors emitted
What does dualistic character of electromagnetic radiation mean?
EM waves at frequencies below ultraviolet are analyzed using wave theory and do not ionize atoms. At UV and above they are analyzed as particles and are capable of ionizing any atoms. That is their dual nature.
Why do cations emit colors when heated in a Bunsen burner flame?
Transitions between electronic energy levels release electromagnetic radiation corresponding to the energy difference between the levels. The heat promotes the electrons to the higher level; when they drop back down to the lower level a specific color of light is emitted.
What is gamma radiation composed of?
It is electromagnetic radiation just like radio, microwaves, visible light etc.. except it has the highest frequency and energy and shortest wavelength of all electromagnetic radiation.
What measurement would you use to measure a stars elemental composition?
If you want to know the elemental composition of a star, you look for the elements' fingerprints. These are in the form of line spectra, since each element has its own particular set of spectral lines. Atoms in the star's atmosphere will absorb their characteristic frequencies from the cavity radiation emitted from the star due to its temperature. Color
