-Instrument Introduction

The diffraction phenomenon that occurs when a beam passes through a single slit, multiple slits, or circular hole is called Fraunhofer diffraction. By using this experimental setup to measure the diffraction intensity of Fraunhofer single slit, multi slit, and circular holes point by point, and hand drawing the intensity distribution curve of diffraction patterns, it not only helps students understand the wave nature of light, but also helps cultivate related experimental techniques and analytical abilities.
