Interference in quantum mechanics

What principle explains the inherent uncertainty in measuring certain pairs of observables in quantum mechanics?

• Heisenberg Uncertainty Principle

• Einstein's Theory of Relativity

• Pauli Exclusion Principle

• Bohr's Correspondence Principle

In quantum mechanics, what term is used to describe the measurable properties of a particle?

• Observables

• Parameters

• Variables

• Constants

What does a wavefunction provide in the context of quantum mechanics?

• Exact position of a particle

• The mass of a particle

• Probabilities of different states

• The speed of light

How does quantum mechanics differ from classical physics in terms of observables?
