Examples of 'emission lines' in a sentence
Meaning of "emission lines"
Emission lines are spectral lines or bright lines that are produced when electrons in atoms or molecules transition from higher to lower energy levels. These lines are specific to certain elements or compounds and can be used to identify and study them. Emission lines are often observed and analyzed in scientific fields such as astronomy and chemistry
