Modeling the color of a substance
The box model can be used as a simple model for the energy levels of dye molecules. Just as a rope as a standing wave can only assume certain wavelengths, an electron locked in a molecule can also only assume certain wavelengths.
As the energy of an electron is related to its wavelength, there are only certain energy levels (quantization of energy). Light is absorbed if the energy of the light corresponds to the energy difference between two energy levels (unless selection rules contradict this).

A simple model for the chemical bond
The box model, which only takes into account the kinetic part of the electronic energy, can be used to represent a simple model for chemical bonding. This model can be used to illustrate the decrease in energy when a bond is formed and the probability densities of the atomic and molecular orbitals.

The videos show the formation of the probability density (AWD). In each fictitious measurement, a position of the electron is represented by a dot. The probability of finding an electron at a certain location is given by the square of the electronic wave function.
