One form of the Heisenberg Uncertainty Principle is ΔxΔpx ≥ h/4π, where Δx is the uncertainty in the system’s location and Δpx is the uncertainty in the system’s momentum along the same coordinate axis. Use this equation to show that exact knowledge of the system is not possible.

Use the Heisenberg uncertainty principle to estimate the uncertainty in momentum resulting from confining an electron to an atom (~10-10 m) and to the size of an atomic nucleus (~10-15 m). Calculate the corresponding uncertainty in the energy (in eV) of the confined electron and briefly comment on the physical implications of your results.

One of the aspects of the uncertainty principle, is that in making measurements, one changes the system being measured. Give an example of this in your everyday existence.

The most basic explanation for the Heisenberg Uncertainty Principle is that the momentum and position of...

The most basic explanation for the Heisenberg Uncertainty Principle is that the momentum and position of a quantum particle is not very distinct when an attempt is made to measure them together. But what is it that causes the uncertainty? Because if there is no change in the momentum, then it would be the same as measuring the two separately. So what causes this change in the instantaneous perceived momentum. A change in mass? Velocity? Or net composition of the...

We know that the uncertainty principle tells us that the product of the standard deviation of energy and the standard deviation in time must always be greater than h-bar. Since there is a unit element of action, is there a unit element of power as well? In other words, if action is always present, then must power always be positive? Clarification: This is not intended to be a question related to people who think that there is "vacuum energy/zero point...

True or False. (a) According to the Heisenberg Uncertainty Principle, it is impossible to know simultaneously both the exact momentum of the electron and its exact location in space. Answer: ____________ (b) According to Born, taking the square root of ψ would give the probability of finding the electron in a certain region of space at a given time. Answer: ____________ (c) Based on the results from blackbody radiation, Max Planck assumed that energy can only be emitted in discrete...
