Question & Answer
Choose the Best Answer
The particle's momentum is also precisely determined
The wave function collapses to a specific eigenstate
Classical mechanics governs the particle's behavior
The particle is always at rest when observed
Understanding the Answer
Let's break down why this is correct
When a particle is measured, its wave function, which describes many possible spots, instantly narrows to one spot. Other options are incorrect because Knowing where a particle is does not make its speed exact; Classical mechanics works for large everyday objects, not for tiny particles.
