Final answer:
Stacking poker chips illustrates wave-particle duality in quantum theory.
Step-by-step explanation:
Stacking poker chips illustrates wave-particle duality in quantum theory. Just like how particles such as electrons can exhibit wavelike behavior, when you stack poker chips, you can think of each chip as a particle that also has wave properties. The chips can exist in multiple positions at the same time, similar to how quantum particles can exist in multiple states simultaneously.
