In addition to the continuous spectrum, a star's spectrum will feature a number of either emission or absorption lines. Atoms produce emission lines when electrons drop from high energy levels to lower ones, emitting photons at specific frequencies in the process. This process adds radiation to the star's spectrum; emission lines are brighte The lines in the hydrogen emission spectrum form regular patterns and can be represented by a (relatively) simple equation. Each line can be calculated from a combination of simple whole numbers. Why does hydrogen emit light when it is excited by being exposed to a high voltage and what is the significance of those whole numbers Figure \(\PageIndex{8}\): The emission spectra of sodium and mercury. Sodium and mercury spectra. Many street lights use bulbs that contain sodium or mercury vapor. Due to the very different emission spectra of these elements, they emit light of different colors. The lines in the sodium lamp are broadened by collisions Figure 12.6: Diagram of the emission spectrum of hydrogen in the visible spectrum. Four lines are visible, and are labelled with their wavelengths. The three lines in the 400 - 500 nm range are in the blue part of the spectrum, while the higher line (656 nm) is in the red/orange part

The Balmer series, or Balmer lines in atomic physics, is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is calculated using the Balmer formula, an empirical equation discovered by Johann Balmer in 1885 Important lines are the hydrogen Balmer lines, lines of neutral and singly ionized helium, iron lines, the H and K doublet of ionized calcium at 396.8 and 393.3 nm, the G band due to the CH molecule, the 422.7 nm neutral calcium line, several metal lines around 431 nm, and the lines of titanium oxide

Molecular lines usually bear little resemblance to the spectral lines associated with their component atoms. For example, Figure 2.21(a) shows the emission spectrum of the simplest molecule known—molecular hydrogen. Notice how different it is from the spectrum of atomic hydrogen shown in part (b) lines of the Balmer series can be observed with the unaided eye. As indicated above, the emission spectra of hydrogen atoms and hydrogen-like (one electron) ions consist of a set of individual lines of specific wavelengths. The numerical values of the wavelengths of these lines fit a particular mathematical pattern called a series A spectral linewidth of 0.33 nm and a polarized emission are unique features of the presented device and to the best of our knowledge could so far not be shown for a Si-LED. In previously demonstrated large area all-silicon devices based on bulk silicon and silicon nanocrystals, the emitted light is not polarized and has a spectral linewidth. These dashed lines represent the different energy levels the electron can have while in the atom. We like representing these energy levels with an energy level diagram. The energy level diagram gives us a way to show what energy the electron has without having to draw an atom with a bunch of circles all the time

Objects known to have double-peaked light curves are plotted only as filled symbols. The curves represent solutions for critical rotation periods for various densities in grams per cubic centimeter: 0.5 (dotted line), 1, 1.5, 2, 2.5, and 3 (dashed line). Regions above and to the left of a given curve are dynamically unstable for a given density Unlike the case with molecular band, in which base spectra for 235 U and 238 U were obtained experimentally (cf.
