When the sodium atom electrons then fall back down to their previous energy level, they emit the difference in energy as light at the D line frequency, creating the bright emission lines.
What produces emission lines bright lines in a spectrum quizlet?
Bright line in a specific location of the spectrum of radiating material, corresponding to emission of light at a certain frequency. A heated gas in a glass container produces emission lines in its spectrum.
What causes the emission of light?
The color of light that is emitted by an atom depends on how much energy the electron releases as it moves down different energy levels. When the electrons return to lower energy levels, they release extra energy and that can be in the form of light causing the emission of light.
What does line emission spectrum mean?
When an electric current passes through a gas, it gives energy to the gas. This energy is then given out as light of several definite wavelengths (colours). This is called a line emission spectrum.
What is a bright line spectrum quizlet?
Bright Line Spectrum. Formed as an excited electron drops back down to the ground state. Electrons (BLS) Absorb energy as they get excited and move up to a higher energy level. Release energy as they drop down to the ground state.
What is an emission line spectrum quizlet?
difference between emission / line and continuous spec. The emission spectrum represents the spectrum of frequencies that occurs when an atom or molecule makes a transition from a high to low energy level.
Which of the following would produce an emission line spectrum?
The emission line spectrum is produced by electrons jumping up in energy level, while the absorption line spectrum is produced by electrons jumping down in energy level.
What is a line spectrum chemistry?
1. A spectrum that consists of narrow, dark, parallel lines on a brightly colored background, produced from a hot light source surrounded by cooler gases that absorb and thus remove certain wavelengths: used to determine the chemical composition of a gas, star, etc.
