Abstract

The traditional Bragg crystal diffraction experiments use X-rays, harming the participants bodies. Therefore, many universities have not offered this basic experiment. Although microwave simulation Bragg experiments can reduce harm, there are still some potential dangers. To solve this dilemma, this article takes ultrasound as the experimental object and uses an artificial simulation of crystals to successfully achieve the Bragg crystal diffraction effect of crystals, which is in good agreement with the theoretical predictions. This experiment is expected to be widely deployed in physics, chemistry, materials, and other science and engineering majors as a basic teaching experiment.
