Quizplus · Accepted Answer

When the difference in energy between adjacent quantized levels becomes vanishingly small, classical physics agrees with quantum physics. This is known as the correspondence principle, which states that the behavior of systems described by quantum mechanics approaches the behavior of classical systems at large quantum numbers.
