Balmer series of hydrogen spectral lines A horizontal diagram of the visible solar spectrum displays colors from violet to red, labeled with wavelength values in nanometers and prominent Fraunhofer lines marking where elements like hydrogen, magnesium, and sodium absorb light. A diagram showing the energy levels of a hydrogen atom, with horizontal lines representing quantum levels N=1 through N=6 and infinity. Vertical red lines indicate electron transitions that produce ultraviolet, visible, and infrared light, labeled as series I, II, and III.
