Ha emission line
WebThe strongest hydrogen emission line, the H-alpha line at 656.3 nm, gives H II regions their characteristic red colour. (This emission line comes from excited un-ionized hydrogen.) H-beta is also emitted, but at approximately 1/3 of the intensity of H-alpha. WebApr 12, 2024 · Saturday 08-Apr-2024 01:20PM HST. (on time) Saturday 08-Apr-2024 09:33PM PDT.
