This statement explains why there is a limit on the line-width of spectral lines, and a generalization of it is given by the Robertson-Schrodinger relation.
This statement explains why there is a limit on the line-width of spectral lines, and a generalization of it is given by the Robertson-Schrodinger relation. This statement follows since the commutator of certain conjugate variables is nonzero, and it can be given as an (*) inequality involving h-bar over two. A thought experiment showing this statement describes the trade-offs in measuring a particle with a microscope, and one usage of it states that both position and momentum cannot be known with exact precision. For 10 points, give this "uncertainty" principle named for a German physicist.

Heisenberg’s uncertainty principle (accept either or both underlined part, but accept just Heisenberg after “uncertainty” is read and prompt if they just try giving uncertainty principle again)
