Final answer:
Wave-particle duality is a phenomenon that only applies to microscopic particles, not macroscopic objects, so the statement is false.
Step-by-step explanation:
The concept of wave-particle duality refers to the ability of particles to exhibit properties of both waves and particles. However, this phenomenon is only evident at the quantum level, affecting microscopic particles such as electrons and photons. When considering objects on the macroscopic scale, such as cars or cricket balls, they do not display wave-particle duality. Therefore, the statement 'True or false: wave-particle duality exists for objects on the macroscopic scale.' would be false.
