![]() ![]() ![]() To precisely measure a wave's energy would take an infinite amount of time while measuring a wave's exact instance in space would require to be collapsed onto a single moment which would have indefinite energy. You could do the same thought experiment with energy and time. Similarly, a wave with a perfectly measurable momentum has a wavelength that oscillates over all space infinitely and therefore has an indefinite position. He put forward the Uncertainty Principle. Depending on the experimental conditions, either quantity can be measured as precisely as desired (at least in principle), but. It states that there is a limit to the precision with which the position and the momentum of an object can be measured at the same time. A wave that has a perfectly measurable position is collapsed onto a single point with an indefinite wavelength and therefore indefinite momentum according to de Broglie's equation. Intrinsic uncertainty was central to the way German physicist Werner Heisenberg, one of the originators of modern quantum mechanics, presented the theory. This is the well-known Heisenberg uncertainty principle for position and momentum. Let's consider if quantum variables could be measured exactly. ![]()
