Final answer:
Quantum physics, while essential for understanding the submicroscopic world, aligns with classical physics at the macroscopic scale due to the correspondence principle. This relationship confirms classical physics rather than denoting a limitation of quantum mechanics.
Step-by-step explanation:
Does Quantum Physics Apply to Macroscopic Objects:
The question concerning if quantum physics is not applicable to macroscopic objects implies several things about the nature of quantum theory. Firstly quantum mechanics is a branch of physics that is necessary to explain phenomena at the submicroscopic level. This means it is significantly different from classical mechanics, which deals with the motion of macroscopic objects like baseballs and cars. The correspondence principle asserts that quantum mechanics descriptions converge with classical mechanics when applied to large, slow-moving objects. This does not imply that quantum mechanics is incomplete; rather it suggests that quantum effects become negligible at the macroscopic scale.
Therefore, the statement implies b) Confirmation of classical physics rather than a limitation of quantum theory. Classical mechanics stands as a valid approximation of quantum mechanics in the macroscopic realm where quantum effects are overshadowed by the larger scale of phenomena. Quantum mechanics does not break down or become invalid; it simply reduces to classical mechanics under certain conditions.
