What is a line spectrum?

electromagnetic spectrum, whose light is a fraction, is a continuous division of wavelengths from ultraviolet to infrared radiation. When electromagnetic radiation in the form of light passes through the material, some of its parts are absorbed or emitted by the medium. When observing this light via the spectroscope, these parts appear as a line spectrum - either a clearly colored emission line on a dark background or a dark absorption line on a clearly colored background. The diffraction grid separated the light on different wavelengths, from purple to red, to a visible extent. This continuous spectrum is issued by bulbs, liquids and gases under high pressure. The two best -known examples are white light with a prism and water drops, which makes a rainbow.

There are two types of line spectrum: emission spectrum and absorbent spectrum. The first is also called Bright Line Spectrum and consists of several clearly colored lines against a dark background. Each line represents a unique wavelength and cellsA thing is unique for this particular element. These lines are emitted when low -pressure gas is in contact with electric discharge.

The

Dark Line Spectrum or Absorption Spectrum is precisely clearly clear lines on each wavelength on a dark background has an absorption spectrum of dark lines on the corresponding wavelengths on a continuous background. This result is the main focus of absorbent spectroscopy and is created by passing light by the gas of the element to be analyzed.

Physicist Niels Bohr introduced in 1913 his idea of ​​why the atomic spectrum has the properties and properties it has. For this purpose, Bohr theorized his own atom, now called the Bohr model. It assumes that electrons can only exist in discrete lanes around the core and that only certain paths are stable, which means that the electron does not radiate radiation. However, radiation is emitted when the electron moveE from orbit with higher energy on the lower orbit.

spectroscopy is an analysis of this phenomenon using a machine called spectroscope. No two elements emit or absorb exactly the same line spectrum, so these observations can be used to determine the elements in the sample. As a result, astronomers have begun to transform their spectroscopes into stars in an effort to determine their composition and the composition of any interstellar medium between a particular star and a country.
