1. In quantum mechanics, what is the term for the discrete packets or bundles in which energy is absorbed or emitted?

2. What is the name for a quantum mechanical system that exists in a probabilistic combination of all its possible states simultaneously until a measurement is made?

3. According to the Heisenberg Uncertainty Principle, which two properties of a particle cannot be known with perfect precision simultaneously?

4. A scientist is observing an electron in an atom. When the electron moves from a higher energy level to a lower one, it releases a specific amount of energy. What form does this released energy typically take?

5. Imagine a photon interacting with an electron, transferring some of its energy and momentum to the electron, resulting in the photon scattering at a different wavelength. What effect demonstrates this particle-like behavior of light?

6. What is the term for the unique set of quantum numbers that describe the state of an electron in an atom, such as its energy level, orbital shape, and spin?

7. Consider two quantum particles that are linked in such a way that measuring a property of one instantly affects the other, regardless of the distance between them. What quantum phenomenon is being described?

8. What is the term for the minimum amount of energy required to remove an electron from the surface of a metal, a key concept in the photoelectric effect?

9. Imagine a quantum particle existing in a state where it is simultaneously in two different locations until observed. What quantum principle describes this ability to be in multiple states at once?

10. Imagine an experiment where a beam of electrons passes through two very narrow slits and creates an interference pattern on a screen, even when electrons are sent one at a time. What fundamental quantum phenomenon does this experiment famously demonstrate?

11. A scientist is trying to precisely measure both the position and momentum of a subatomic particle. As they attempt to measure one property more accurately, their ability to know the other property accurately decreases. What quantum principle are they encountering?

12. Consider a scenario where a quantum particle passes through a potential energy barrier even though it doesn't have enough classical kinetic energy to do so. What quantum effect allows for this seemingly impossible penetration?

13. Which concept suggests that the act of observing or measuring a quantum system can affect its state, causing it to "collapse" into a definite outcome?

14. What fundamental concept in quantum mechanics states that a particle can exhibit properties of both a wave and a particle?

15. What does a "wave function" in quantum mechanics describe?
