Hψn=EnψnHψn=Enψn

Where H is the operator Hamiltonion, the corresponding value is a collection of wave (eigen)functions.

Consider the basic quantum system of a single particle in a 1D box with infinite walls and zero potential within the box, if you're unfamiliar with your own values.

The system operator in Hamilton is:

H=2d22mdx2H=\frac{ℏ2d^2}{2mdx^2}

Equations in Schrödinger (SE)

2d22mdx2ψn(x)=Enψn(x)\frac{−ℏ2d^2}{2mdx^2}ψn(x){}=E_nψ_n(x)

ψn(x)=Csinnπxaψ_n(x)=C sin \frac{n\pi x}{a}

The length of the box is n=1,2,3,... and a.

En=n2π222ma2E_n=\frac{n^2π^2ℏ^2}{2ma^2}

Where n=1,2,3, − the SE's own functions and the En's own values.
