Science Homework Help

A friend tells you they are confused: they heard that quantum mechanics says everything is both a wave and a

particle. What do you think is the most helpful single sentence response?

A. Well, people say that because quantum objects follow a set of rules completely different from any classical phenomena, but with some features that look kind of like those of classical waves and some that look kind of like those of classical particles.

B. Well, large enough objects behave like classical particles, but small enough objects are quantum and behave like classical waves.

C. Yes, it’s confusing but true: a quantum mechanical particle is like a classical wave and a classical particle at the same time.

D. Well, objects behave like classical particles when you measure their positions, but like classical waves when you don’t.
