Final answer:
Wave-particle duality refers to quantum objects exhibiting both wave-like and particle-like properties. This duality is not observable in macroscopic objects, making the statement false.
Step-by-step explanation:
The concept of wave-particle duality applies to quantum objects such as electrons and photons, which exhibit both wave-like and particle-like properties. However, for objects on a macroscopic scale, such as baseballs or cars, this duality does not manifest in a way that can be observed or measured with current technology. The behaviors of macroscopic objects are very well described by classical physics, and they do not exhibit the dual nature inherent in quantum objects. Therefore, the statement that wave-particle duality exists for objects on the macroscopic scale is false.
