Document Summary
Sketch spectral graph: bright line/ emission continuous dark line/ absorption. Stars generate energy and pass through ambient material give an example: Stars describe situation that produces each spectrum, according to kirchhoff"s laws. Sketch a blackbody spectrum for objects with the following temperatures: Describe the physical conditions that allow stars to generate a dark line or absorption spectrum: Stars are objects that generate their own energy in all wavelengths. The interior of the star , the photo is going to be absorbed. Adom removes specific wavelength as a electrons jump to higher levels. You have the dark lines because the atoms presented in the remove certain wavelengths that will create the dark line spectrum. Allows that electrons are going to be in a higher state stars are objects that generate their own energy. At the edge of the star, you have gas so there is a mix of all different kind of atoms, it"s a cooler gas.
