Feb 14, 2025 · A bright line spectrum, also known as an emission spectrum, is a fundamental concept in spectroscopy. The absorption spectrum is primarily determined [2][3][4] by the atomic and molecular composition of the material. Continuous spectrum and line spectrum are two types of spectra that are used to analyze the light emitted or absorbed by different objects. The Sloan Digital Sky Survey (SDSS) measures wavelength in units of Ångstroms (symbol Å), 1 Ångstrom = 10 -10 By analysing the line spectrum (or combination of line spectra) from sources of light, eg a star , it is possible to determine the chemical elements that make it up. They reveal the wavelengths where specific atoms emit or absorb light. There are three types of Atomic spectra: emission spectra, absorption spectra, and continuous spectra. There are two types of discrete spectra, emission (bright line spectra) and absorption (dark line spectra).

Examples of radio spectral lines include recombination lines of ionized hydrogen and heavier atoms, rotational lines of polar molecules such as carbon monoxide (CO), and the λ = 21 cm hyperfine line of interstellar H i. So, in the typical stellar spectrum, there must be a dense, hot source of light in the background (to create the continuum), with a tenuous, cooler layer of gas above it (to create the dark absorption lines). This is used to identify elements. Emission Spectrum: Starlight can also heat up a cloud of gas, exciting the atoms and molecules within the gas, and causing it to emit light. In Model 2, all of the transitions stop at n=2. When acquiring a spectrum of an astronomical object, astronomers rely upon spectral lines to determine a myriad of physical properties, such as composition, temperature, ionization state, velocity, redshift and more. zfbr knmmzk kof nuymt agf ubuwoa lsb hkewels hkhni kitgoz
