Why is there a line spectrum over a continuous spectrum in a spectroscope?

The lines in a spectroscope tell what element(s) are being observed. The continuous color are background noise or put there for a reference.

What is the use of a spectroscope?
A spectroscope is used to measure properties of light over a specific portion of the electromagnetic spectrum.
What does it mean to say a line is continuous?
A continuous line goes on forever, the mathematic symbol for infinity is a sideways number 8 because U'r able to draw that symbol infinitely over & over again. A normal line starts with a point A & finishes with the point B, but a line that is continuous has no point B.
What is the difference between a continuous spectrum an a line spectrum?
Dispersion, the separation of visible light into a spectrum, may be accomplished by means of a prism or a diffraction grating. Each different wavelength or frequency of visible light corresponds to a different color, so that the spectrum appears as a band of colors ranging from violet at the short-wavelength (high-frequency) end of the spectrum through indigo, blue, green, yellow, and orange, to red at the long-wavelength (low-frequency) end of the spectrum. In addition to visible light, other types of electromagnetic radiation may be spread into a spectrum according to frequency or wavelength. The spectrum formed from white light contains all colors, or frequencies, and is known as a continuous spectrum. Continuous spectra are produced by all incandescent solids and liquids and by gases under high pressure. A gas under low pressure does not produce a continuous spectrum but instead produces a line spectrum, i.e., one composed of individual lines at specific frequencies characteristic of the gas, rather than a continuous band of all frequencies. If the gas is made incandescent by heat or an electric discharge, the resulting spectrum is a bright-line, or emission, spectrum, consisting of a series of bright lines against a dark background. A dark-line, or absorption, spectrum is the reverse of a bright-line spectrum; it is produced when white light containing all frequencies passes through a gas not hot enough to be incandescent. It consists of a series of dark lines superimposed on a continuous spectrum, each line corresponding to a frequency where a bright line would appear if the gas were incandescent. The Fraunhofer lines appearing in the spectrum of the sun are an example of a dark-line spectrum; they are caused by the absorption of certain frequencies of light by the cooler, outer layers of the solar atmosphere. Line spectra of either type are useful in chemical analysis, since they reveal the presence of particular elements. The instrument used for studying line spectra is the spectroscope.
What is a line graph?
A continuous graph that shows change over time.
What would hydrogens spectrum have to be to become a continuous spectrum?
In order for a hydrogen atom to have a continuous spectrum, the oscillation would have to be incoherent. In other words, there would be no fixed or steady state oscillation. In addition, the change in state of the oscillator would have to be incoherent. We know that the energy that is radiated from a hydrogen atom is due to changes in the energy states of the atom. Therefore, each of the states that the atom would have to reach must be perfectly random. This would produce a nearly continuous spectrum over a certain range in frequencies or wavelengths.
What does the term continuous mean in science?
Continuous means without interruption. For example, a continuous longitudinal study collects data from subjects over their full lifespan without breaks. Another example is a 'continuous line' is solid, while a 'dashed line' is a series of short lines.
When do you use a broken line graph?
you use a broken line graph usually for showing continuous data (data with growth over time)
How is a line line segment and a ray different?
line segments have two definite points, A and B, a ray has has only one definite point and the over indefinite point is a continuous line
What is meant by precedence of lines?
This phrase is used when obtaining orthographic views. It is common for one type of line to overlap another. For instance, a continuous line might be in the same location as a hidden line. For this reason, there is an order of precedence in terms of drawing conventions and standards. Typically the continuous line will have greater value or will "take precedence" over the hidden line, while the hidden line will take precedence over the centerline.
What is a Electromagnetic spectrum?
The combination of different colours due to the dispersion of sun light is called spectrum. This type of spectrum is called continues or line spectrum.
What is line of sight communication?
Line of sight communication is in the VHF and higher frequencies of the RF spectrum where the wavelength is to short to pass over structures and hills, the transmitter and receiver antennas must be in line of site
What is a continuous production process?
A continuous production process is a series of steps that produces the same product over and over without interruption. An oil refining plant is one example. It pumps out oil continuously. An automobile assembly line would be another example.
