Question: What does the Heisenberg Uncertainty Principle state?

Options:

1. Energy and mass are interchangeable
2. The position and momentum of a particle cannot both be precisely known
3. Electrons can exist in multiple states simultaneously
4. Light behaves both as a wave and a particle

Correct Answer: The position and momentum of a particle cannot both be precisely known

Solution:

The Heisenberg Uncertainty Principle states that the position and momentum of a particle cannot both be precisely known at the same time.
