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.

Use the Heisenberg uncertainty principle to calculate Δx for an electron with Δv = 0.380 m/s. By what factor is the uncertainty of the (above) electron's position larger than the diameter of the hydrogen atom? (Assume the diameter of the hydrogen atom is 1.00×10-8 cm.) Use the Heisenberg uncertainty principle to calculate Δx for a ball (mass = 108 g, diameter = 7.90 cm) with Δv = 0.380 m/s. The uncertainty of the (above) ball's position is equal to what...

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...

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.

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...
