 This paper broadly explains the phenomenon of Electromagnetically Induced Transparency (EIT) through a simple classical coupled oscillator model. By drawing an analogy between the three-level structure in atomic systems and the coupled oscillator system, it first demonstrates how a classical physics model can simulate the transparency phenomenon caused by quantum interference. Subsequently, through theoretical analysis and numerical simulations, the similarities between coupled oscillators and EIT are explored, leading to the development of a general method for understanding the core mechanism of quantum coherence effects using classical coupled models. Finally, based on this method, the phenomenon of induced transparency in optomechanical systems, namely Optomechanically Induced Transparency (OMIT), is further investigated, showcasing the theoretical significance of classical mechanical models in integrating advancements in frontier physics into university-level physics education and in understanding modern scientific research outcomes.
