Subject | has specie | has definition | has synonym | is a kind of | has wavelength |
---|---|---|---|---|---|
absorption edge | Sudden rises superposed on the smooth decrease of the curve of the attenuation coefficient, which cause the curve to have a typical sawtooth aspect. They generally occur at the limit of spectral lines. | spectral feature | |||
Balmer jump | hydrogen (H I) | The sudden decrease in the intensity of the continuous spectrum at the limit of the Balmer series of hydrogen at 3646 Å, representing the energy absorbed when electrons originally in the second energy level are ionized. | Balmer discontinuity | absorption edge | 3646 Å |
