If A, B and C are Hermitian operators, determine if the following combinations are Hermitian: 1 A + B 2 1 2i [A, B] 3 (ABC − CBA) 4 A 2 + B 2 + C 2 5 (A + iB)
A nucleus has a radius of 4 Fermis. Use the uncertainty principle to estimate the kinetic energy for a neutron localized inside the nucleus. Do the same for an electron.
A nucleus has a radius of 4 Fermis. Use the uncertainty principle to estimate the kinetic energy for a neutron localized inside the nucleus. Do the same for an electron.
Estimate the Hydrogen Ground State Energy
Is it possible to see inside an atom?
A hydrogen atom is 5.3 × 10−10 m in radius. Use the uncertainty principle to estimate the minimum energy an electron can have in this atom.
A typical atomic nucleus is about 5 × 10−15 m in radius. Use the uncertainty principle to place a lower limit on the energy an electron must have if it is to be part of a nucleus.
What is a quantum?
Compare QM and classical results.
