The emission spectrum can be used to determine the composition of a material
Spectral analysis is based on the study of emission spectra.
Because an emission spectrum is specific to an element.It can be used to identify the element
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
Yes.
The atomic level is affected by the movement of electrons so as to give rise to the observed energy. This is what is used to explain the atomic emission spectra.
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.

There are three main types of infrared spectra: absorption spectra, emission spectra, and reflection spectra. Absorption spectra are produced when a material absorbs infrared energy, emission spectra are produced when a material emits infrared radiation, and reflection spectra result from the reflection of infrared radiation off a material.
Two common sources of continuous spectra used in emission spectroscopy are the electrical discharge lamps and the incandescent lamps. Electrical discharge lamps, such as the mercury vapor lamps, produce continuous spectra due to the excitation of atoms or molecules in the gas discharge. Incandescent lamps, on the other hand, produce continuous spectra because of the thermal emission from the hot filament.

an emission spectrum that consists of a continuum of wavelengths.
The heat of the flame excites the metals ions, causing them to emit visible light. The characteristic emission spectra can be used to differentiate between some elements.SO the characteristic emission spectra of Barium contains wavelengths corresponding to green color.
The lines are at the same frequencies
Some examples of every day objects with vivid emission spectra are the following: glass, water droplets, and chameleon paint jobs.
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.

Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
Emission spectrometry is an old and largely known method for quantitative and qualitative analysis of elements.
