Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray
That would be the degree of luster.
The electromagnetic spectrum is the all the frequencies possible outiside of the visible spectrum such as ultraviolet.
Light coming up from the centre of the Sun goes through the outer layer where it encounters absorbtion by elements in the outer layer, and this gives rise to absorbtion lines in the spectrum.
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
White is technically the reflection of all colours on the spectrum while black is all colours' absorbtion.
It doesn't. An absorbtion spectrum is produced when it absorbs energy. An emission spectrum is produced when it lets the energy go again. The energy changes are associated with the element's electrons going up to higher energy levels and then dropping down again.
By looking at the spectrum of its light and finding out which absorbtion lines can be seen. The lines correspond to specific elements in the outer parts of the star.
Less reflection, more absorbtion. More absorbtion, greater efficiency.

The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
