A particle is trapped in an infinite potential well. Describe what happens to the particle’s ground-state energy and wave function as the potential walls become finite and get lower and lower until they finally reach zero (U = 0 everywhere).

4. Briefly explain what is meant by the term "potential GDP," and identify the alternative term that is considered to be synonymous from a macroeconomic perspective with "potential GDP." Potential GDP is defined as the maximum quantity that an economy can produce given its existing levels of labor, physical capital, and technology, in the context of its existing market and legal institutions. Potential GDP is also called full-employment GDP.

The infinite potential well has zero potential energy between 0 and a, and is infinite elsewhere. a) What are the energy eigenstates of this quantum system, and what are their energies? In the case of a discrete spectrum, explain where the quantization comes from. b) Suppose we take the wavefunction at a given time to be an arbitrary function of x that is symmetric around the center of the well (at x = a/2). Is this a stationary state in...
