Distinguish Between Emission And Absorption Line Spectra.

1.	Distinguish Between Emission And Absorption Line Spectra.
Answer» An EMISSION line spectrum of an element CONSISTS of coloured lines on a dark background while an absorption spectrum consists of dark lines on a coloured background at the same discrete wavelength positions for the same element. For emission spectra, electrons TRANSIT from a HIGHER energy level to a LOWER energy level. For absorption spectra, electrons transit from a lower energy level to a higher energy level. An emission line spectrum of an element consists of coloured lines on a dark background while an absorption spectrum consists of dark lines on a coloured background at the same discrete wavelength positions for the same element. For emission spectra, electrons transit from a higher energy level to a lower energy level. For absorption spectra, electrons transit from a lower energy level to a higher energy level.
