Are the spectral lines always in the same order ROYGBIV?
The arrangement of the spectral colors are determined by how the human eye and brain work. There is no clear reason to believe that different people or animals see the spectrum the same. In fact it is easy to show that they don't.
Lines that have the same slope in math?
Lines that have the same slope are said to be parallel lines.
What are symmetry lines?
Lines which lie on the same plane and have the same length are known as symmetry lines
Lines in the same plane that do not intersect are what?
Parallel lines. they never intersect and lie on the same plane.parallel lines
What lines do not intersect but are on the same plane?
Lines which are parallel. All other lines on the same plane eventually intersect.
Does Every element and compound in nature have a unique set of spectral lines?
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
The spectral lines produced by elements all look the same?
For A+ the answer is False. Your Welcome fellow cheaters xD.
Why do sodium oxide and sodium chloride burn the same color?
Because important is the metal (sodium) and his spectral lines.

What is the best way to determine a galaxy's redshift?
Take a spectrum of the galaxy, and measure the difference in wavelength of spectral lines from the wavelengths of those same lines as measured in the laboratory
What are the dark lines in a stellar spectrum are called?
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.
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.
Would you expect sodium fluoride to produce the same color as sodium chloride and why?
If you think to flame test the color is the same; the important factor is sodium with his spectral lines.
When astronomers look for evidence of hydrogen gas in the spectra of the Sun the planets and nearby stars the positions of the spectral features or lines due to hydrogen are different or the same?
They are the same.
How do Spectra from neutral atoms compared with spectra from ionized atoms of the same element?
have different sets of spectral lines. :) u got to love astronomy
Why will all sodium compounds emit the same color flame?
Because important is the metal - sodium - and his most important spectral lines - yellow region.
What nearby star is in the same spectral class as the sun?
Alpha Centauri A - It is 4.365 light years away and has a spectral class of G2V the same as our Sun
