Answer to Question #119946 in Quantum Mechanics for Dheeraj

Question

The energy density of states of an electron in a one diamensionalpotential well of infinitely high walls is? (No need to do the whole calculation, i know all the formulas of energy and wave function for it. just show me only for the energy density)

Answer 1

The energy for state n in one-dimensional infinite well of width L is

$$E=\frac{h^2}{8mL^2}n^2$$
