Atomic orbitals are presented as solutions of the Schrödinger equation, but it is difficult for beginners to understand that atomic orbitals represent the shape of electron waves. The cross section of the atomic orbitals resembles the vibration patterns of a disk with a fixed circumference. Therefore, in order to increase interest in atomic orbitals and deepen understanding of orbital shapes, a device for demonstration experiments was developed that can generate Chladni figures similar to various types of atomic orbitals.
