Final answer:
Wave-particle duality is a concept of quantum mechanics that does not apply to macroscopic objects. It's significant only for microscopic quantum entities, hence the answer is false.
Step-by-step explanation:
The True or False question you've asked pertains to the concept of wave-particle duality, which is a fundamental principle of quantum mechanics. This principle states that every particle or quantum entity may be partly described in terms not only of particles, but also of waves. For macroscopic objects, which are objects we can see and touch, wave-particle duality does not apply. It is a property of particles at the quantum level, such as electrons and photons. Therefore, the correct answer to your question is:
a. false
Macroscopic objects do not display wave-particle duality; this phenomenon is significant only at the microscopic scale, where quantum effects are non-negligible.
