Quizplus · Accepted Answer

Natural line broadening is a consequence of the uncertainty principle, which states that the more precisely the position of a particle is known, the less precisely its momentum can be known, and vice versa. This principle leads to a fundamental limit on the precision with which certain pairs of physical properties, such as energy and time, can be simultaneously known, resulting in the natural broadening of spectral lines.
