Wave function collapse is a fundamental concept in quantum mechanics where a quantum system's wave function, initially in a superposition of several eigenstates, reduces to a single eigenstate due to measurement. This process is central to understanding the transition from quantum possibilities to definite outcomes observed in classical physics.

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

Superposition is a fundamental principle of quantum mechanics where a quantum system can exist in multiple states simultaneously until it is measured. This principle leads to the probabilistic nature of quantum mechanics, where the act of measurement collapses the system into one of the possible states.

Eigenstates are specific quantum states of a system that correspond to definite values, or eigenvalues, of an observable, such as energy or momentum. They are fundamental in quantum mechanics because they provide a basis for describing the state of a quantum system and predicting measurement outcomes.

Measurement is the process of quantifying an object's characteristics, allowing for comparison, analysis, and understanding within a defined context. It involves the use of standardized units and tools to ensure accuracy and consistency across different observations and experiments.

Classical physics encompasses the principles and theories developed before the advent of quantum mechanics and relativity, primarily focusing on macroscopic phenomena. It includes foundational laws and concepts that describe the motion of bodies, forces, energy, and the properties of matter and waves in a deterministic framework.
