Calculate the energy of the first excited state of an electron confined to a one-dimensional box with . (3 + 2 = 5 marks)
(b) Define degeneracy and calculate the degeneracies of the first five energy levels for a particle of mass confined to a cubic box of edge length
.
We will solve the problem numerically, step by step. --- ### (a) Energy of the First Excited State in a 1D Box For a particle confined in a 1D box of length \( L \), the energy levels are given by the particle in a box equation: \[ E_n = \frac{n^2 h^2}{8mL^2} \] where: - \( n \) is the quantum _____ ______ _____ __________ ___ _____ _____ _____ ___.
