2. Two possible wave functions for states of a particle, with definite energies E_1 and E_2 are: see attachement for equations.
- Explain why these are called stationary states.
- Calculate the frequency of the oscillations if E_1 = 1.2eV and E_2 = 0.3 eV.
- From a semi-classical perspective, what would be the consequences of such oscillations if the particle were electrically charged?
- The expectation value of the energy-squared for this state is: see attached. Calculate the uncertainty in the energy.
3. A particle of mass m moves in a two-dimensional simple harmonic oscillator potential of the form (see attached), where W_o is a constant. Write down the two-dimensional version of the time-independent Schrodinger equation for this situation.
- Consider a stationary-state solution of the time dependent equation of the form (see attached), where n_x and n_y are quantum numbers. What is the energy of this state (see attached), in terms of n_z, n_y, and W_o?
- What is the degeneracy of the state with energy (see attached).
- See attached for second last question.© BrainMass Inc. brainmass.com October 9, 2019, 5:38 pm ad1c9bdddf
