Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following best describes wave-particle duality?
Particles can only behave as waves.
Waves can only behave as particles.
Particles and waves are distinct entities.
Particles can exhibit both wave-like and particle-like properties.
2. The Heisenberg Uncertainty Principle states that:
The more precisely one property is measured, the more precisely another can be predicted.
It is impossible to precisely measure both the position and momentum of a particle simultaneously.
Energy is always conserved in quantum systems.
All particles have a definite position and momentum at all times.
3. The smallest indivisible unit of energy is called a .
4. Quantum describes the phenomenon where two or more particles become linked in such a way that they share the same fate.
5. According to the Bohr model, electrons orbit the nucleus in specific energy .
