How is a bright line spectrum produced?
Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…
What causes the bright lines in the emission spectrum of an element to occur?
What causes the bright lines in the emission spectrum of an element to occur? Photons are emitted when electrons jump from a higher-energy to a lower-energy state. Photons are absorbed when electrons jump from a lower-energy to a higher-energy state.
How is an emission line spectrum produced quizlet?
Emission spectra are produced when photons are emitted from atoms as excited electrons return to a lower energy level. – All forms travel at the same speed of light but have different wavelengths. – The higher energy forms have shorter wavelengths and higher frequencies.
What is another name for a bright line spectrum?
…a pattern is called an emission, or bright-line, spectrum. When light passes through a gas or cloud at a lower temperature than the light source, the gas absorbs at its identifying wavelengths, and a dark-line, or absorption, spectrum will be formed.
What is the difference between a bright line spectrum and an absorption spectrum?
Emission lines refer to the fact that glowing hot gas emits lines of light, whereas absorption lines refer to the tendency of cool atmospheric gas to absorb the same lines of light. When light passes through gas in the atmosphere some of the light at particular wavelengths is scattered resulting in darker bands.
Which of these is the best definition for an emission spectrum?
emission spectrum in British English noun. the continuous spectrum or pattern of bright lines or bands seen when the electromagnetic radiation emitted by a substance is passed into a spectrometer. The spectrum is characteristic of the emitting substance and the type of excitation to which it is subjected.
What is a line-emission spectrum quizlet?
line-emission spectrum. a series of specific wavelengths of emitted light created when the visible portion of light from excited atoms is shined through a prism. continuous spectrum. the emission of a continuous range of frequencies of electromagnetic radiation.
What is a bright line spectrum used for?
Spectral lines are often used to identify atoms and molecules. These “fingerprints” can be compared to the previously collected “fingerprints” of atoms and molecules, and are thus used to identify the atomic and molecular components of stars and planets, which would otherwise be impossible.
What is meant by bright line spectrum?
: an emission spectrum consisting of bright lines against a dark background.
What are the similarities and differences between the continuous spectrum and a bright line spectrum?
A continuous spectrum is represented by a rainbow of colors and multiple wavelengths while a line spectrum is only a few colors and very few wavelengths. The lines on a spectrum are determined by the movement of electrons in energy levels.
