Question:

It can be shown that the allowed energies of a particle of mass m in a two-dimensional square box of side L are 

Enm h 8mL (n +1)

The energy depends on two quantum numbers, n and I, both of which must have an integer value 1, 2, 3,.... 

a. What is the minimum energy for a particle in a two- dimensional square box of side L? 

b. What are the five lowest allowed energies? Give your values as multiples of Emin.
