The Correspondence Principle is a fundamental concept in physics, primarily associated with the transition from classical mechanics to quantum mechanics. It states that the behavior of quantum mechanical systems must converge to classical physics in the limit of large quantum numbers or when the system is described by macroscopic quantities. In essence, the Correspondence Principle asserts that any new theoretical framework (like quantum mechanics) should reproduce the results of an older, well-established theory (like classical mechanics) in situations where the older theory is applicable.
