The Modern Atom

The Modern Atom. Emission Line Spectra. When an electrical voltage is passed across a gas in a sealed tube, a series of narrow lines is seen. These lines are the emission line spectrum . The emission line spectrum for hydrogen gas shows three lines: 434 nm , 486 nm , and 656 nm .

The properties of bulges

The properties of bulges. Bulges are some of the densest stellar systems. They can be flattened, ellipsoidal or bar-like. The surface brightness of a bulge is often approximated by the Sersic law: I(R) = I(0) exp{-(R/R 0 ) 1/n }
