What is the purpose of the slit in the spectroscope?
The purpose of the slit in the spectroscope is to regulate the amount of light that comes in. Without the slit, light would come from various angles.
What do the bright lines in a bright light spectrum tell us?
to identify elements
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
How was helium identified on the sun with a spectroscope?
Every element, when heated, sends out light with characteristic spectral lines. These same lines are also absorbed when the element is present in an atmosphere between a light source and the observer. When studying spectral lines of the sun some lines were noted that were not known on earth, from which we concluded that there must be an inknown new element. Which was subsequently found on earth.
Why do no two elements produce the same pattern of bright lines?
differing numbers of electrons
Why is the spectroscope scale illuminated?
The reason that the spectroscope scale is illuminated is so that you know where the wavelengths of the lines are at. It also determines the measurement of the absorption bands.
What is a tool that separates a star's light into color bands and dark lines?
a spectroscope
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 purpose of the slit in the spectroscope?
The purpose of the slit in the spectroscope is to regulate the amount of light that comes in. Without the slit, light would come from various angles.
What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.

How many times has Vesuvius eruptid?
bright yellow with white lines but some times ornge with white lines.
What fixture or device receives discharge from indirect waste piping?
Condensation lines, commercial dishwashers, etc. receive discharge from indirect waste piping.

What you observe if light from argon gas were passed?
A series of discrete bright lines.
Why is discharge line leaving outside unit cold on central ac?
The expansion device inside the outside unit expands the refrigerant gas and as a result, the discharge lines chills
