The co-ordinate θ in ψ(r,θ,ϕ) is the angle from the positive Z-axis (the north pole), representing latitude.

What does the Schrodinger equation represent?

The Schrodinger equation is used to find the allowed energy levels of quantum mechanical systems (such as atoms, or transistors). The associated wavefunction gives the probability of finding the particle at a certain position.

What does the wave function ψ represent?

Wave Functions. A wave function (Ψ) is a mathematical function that relates the location of an electron at a given point in space (identified by x, y, and z coordinates) to the amplitude of its wave, which corresponds to its energy.
