SUMMARY

The essence of light is a kind of electromagnetic radiation, which is a form of matter movement. It is the external expression of the internal movement of molecules and atoms of matter in the form of radiated energy. It was through observing and studying the spectrum of hydrogen atoms that people began to study the atomic structure. YMP-6116 atomic spectroscopy experimental device mainly includes: light sensor, rotation sensor, slit, lens, guide rail, bracket, light source (hydrogen lamp, helium lamp, mercury lamp, sodium lamp, etc.) light source. The experimental device has a simple structure with convenient light path adjustment, allowing students to fully understand and master the principles and structure of spectroscopic instruments. At the same time, the device also uses advanced sensor technology and intelligent software to achieve continuous data collection and real-time drawing of experimental data curves, powerful equation editing functions, which greatly improve the efficiency of experiments, allowing students to devote more energy to the principle learning, operation, data analysis and result discussion of the experiment itself, and be more able to have a thorough academic qualification, understanding and mastery of experiments .
