Question

a particle in cubic shaped box with infinitely hard walls whose edges are a,b&c respectively one corner of cube at origin and edges parallel to the axes the wave function of particle?

Answer 1

The function sought is as follows:

Ψ(x,y,z) = (8/abc)^1/2 *sin(πn₁x/a)*sin(πn₂y/b)*sin(πn₃z/c)
