What else can I help you with?
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.
What is multiplicity of spectral line?
Multiplicity of a spectral line refers to the degeneracy or number of possible states that can produce a given spectral line in a spectrum. It is related to the possible orientations of the electron spins in an atom that can lead to the same energy level transition. The higher the multiplicity, the more ways there are for a particular transition to occur, contributing to the line's intensity.
You observe the same spectral line in two stars that are identical in every way except that one rotates faster than the other How does the spectral line differ between the two?
The spectral line in the star that rotates faster will be broader due to the Doppler effect caused by the varying speeds of rotation on different parts of the star. The faster rotation creates a wider range of velocities contributing to the broadening of the spectral line compared to the slower rotating star.
Do two opposite rays always form a line?
No, they could by parallel but not the same line.
A trend line on a graph is always the same as the line of best fit?
No.
Two stars of the same spectral class must have the same what?
Two stars of the same spectral class must have the same temperature and color. This classification system groups stars based on their temperature, with each spectral class representing a specific range of temperatures.
Are line segments have same sides'?
Not always
What is the difference between collinear and non collinear?
In order for three or more points to be collinear, they must lie on the same line. Two points would always be collinear. Noncollinear are points that do not lie in the same line.
Which figure always has the same line of symmetry?
square
Would the line of breakers at a particular beach always form at the same distance from shore?
The line of breakers at a particular beach will not always be the same distance from shore because the tides are always slightly different
Is a trend line on a graph always the same as the line of best fit?
Usually yes.
Line segments that are always the same distance apart?
Parallelogram
