Continuous spectrum with dark lines where light is absorbed?
dark-line spectrum...
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
Definition hidden line?
Hidden lines are broken lines that indicate the lines not seen in a certain perspective.
Does an o have a line of symmetry?
It not just has a line of symmetry; a perfect circle has an infinite number of lines of symmetry.
How many central atom of H2O?
The water molecule is one oxygen atom connected to two separate hydrogen atoms. The three are not in a perfect straight line, though there is symmetry through the central oxygen atom.
What kind of spectrum do dark lines appear against a bright a bright background of colors ranging from red to blue?
Dark-line spectrum is a "photo-negative" of emission spectrum. It is the gaps that appear in precisely the same location as corresponding bright lines. produced by a cool gas with a hot solid and you
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
What does the term bright line spectrum mean?
A bright line spectrum refers to the pattern of distinct and bright lines of different colors that are produced when an element is excited and emits light. Each element has a unique bright line spectrum that can be used to identify the element through spectroscopy.
Why can the bright-line spectrum of an element be used to identify an element?
The bright-line spectrum of an element is unique because it consists of specific wavelengths corresponding to the energy levels of electrons transitioning in that element's atoms. Since each element has a distinct arrangement of electrons, the pattern of lines in its spectrum is like a fingerprint, allowing scientists to identify the element based on the specific wavelengths present in the spectrum.
What causes spectra lines?
Absorption of energy at atom energy levels cause the line spectrum.
Why does hydrogen have the simplest bright light spectrum?
Because the bright line spectrum is generated by the transition of electrons in the atom among higher and lower energy levels, and no other atom of any other element has less than one electron in it.
How are the continuous bright line spectrum and spectral lines similar?
In a continuous spectrum, you see every color in visible light from wavelengths around 380 nm to 780 nm. The bright light spectrum has only light at specific wavelengths, forming narrow regions of lights. This is characteristic of a particular substance, emitting these lights from its unique electron configuration. Light at specific wavelengths is emitted for different substances, but not a continuous rainbow.
What does a star's dark-line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
What spectrum is produced by a hot gas under low pressure and appears in a series of bright lines?
An emission spectrum is produced by a hot gas under low pressure, which appears as a series of bright lines. Each bright line corresponds to a specific wavelength of light emitted when electrons transition from higher to lower energy levels within the atoms of the gas.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
How is the bright light spectra of elements produced?
An emission or absorption line in a spectrum that arises when an electron moves between two energy levels in an atom. A jump to a higher level requires an input of energy, and produces a dark absorption line. A drop to a lower level releases energy, producing a bright emission line.
When is the characteristic bright-line spectrum of an atom produced?
In the laboratory in a flame test. Electrons are excited to higher energy levels and when they fall back light is emitted. The frequency (colour), v is related to the energy by Plancks equation, E=hv
