Line spectra are sharp lines of definite wavelengths. It is the characteristic of the emitting substance. It is used to identify the gas. Atoms in the gaseous state, i.e. free excited atoms emit line spectrum.

These systems are especially associated with atoms and sometimes with the molecules or atomic nuclei. Due to the presence of wavelengths, the spectrum of incandescent solids are considered to be continuous.

Some sources emit only certain wavelengths and produce an emission spectrum of bright lines with dark spaces between. Such line spectra are characteristic of

This is its atomic line emission spectra. Electrons exist in distinct energy levels in the atom. They can move up in energy by absorbing a photon or move down in energy by emitting a photon.

Line spectra are characteristic of the elements that emit the radiation. A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. Line spectra from He-like ions are arguably the most important X-ray astrophysical diagnostics for temperature, density, absorption, and tests of ionization equilibrium.

This kind of spectrum is known as a dark line or absorption spectrum. The Bohr model of the atom can be used to understand how these different types of spectra are produced. Emission or absorption of light only takes place when a photon has an energy equal to the difference in quantised energy states that an electron can occupy in its orbit around the nucleus. 2018-04-16 · 6.

In stock and ready to ship. Stellar and emission line spectra Laboratory exercise - Astrophysical Spectra Magnus Gålfalk Stockholm Observatory 2007 1. 1 Introduction Almost everything we know about the universe outside our solar system comes from informa-tion provided by light, or more precisely, electromagnetic radiation. Each line in the emission spectrum corresponds to an electron moving from a higher energy level to a lower energy level. To do this it emits photon of light the energy of the photon of light is equal to the difference in the energy of the two energy levels. h = the Plank constant 6.63 x 10-34 J s; CHARACTERISTICS X- RAY LINE SPECTRUM : When the target of an X-ray tube is stuck by energetic electrons, it emits two kinds of X-ray radiation. One of then has a continuous spectrum whose intensity distribution in wavelength depends entirely on the tube voltage.
