Question

The energy of free particle in 3D is ​

Answer 1

Answer:

Degeneracy in a 3D Cube The ground state has only one wavefunction and no other state has this specific energy; the ground state and the energy level are said to be non-degenerate. However, in the 3-D cubical box potential the energy of a state depends upon the sum of the squares of the quantum numbers (Equation 18).
