For a wave function describing the state of an isolated system in 1D, does a wave function describe a system completely?
A wave function, also known as a probability amplitude, is a mathematical function used to describe the quantum state of a particle or system. It represents the probability of finding a particle at a specific position and time.
No, a wave function is not a complete description of a particle. It only represents the probability of finding a particle at a certain position and time. Other physical quantities, such as momentum and energy, are also needed to fully describe a particle.
No, a wave function cannot be directly observed or measured. It is a mathematical concept that represents the probability of finding a particle in a certain state. However, the effects of a wave function can be observed through experiments and measurements.
The completeness of a wave function is determined by its ability to accurately predict the behavior of a particle. If a wave function can accurately predict the probability of finding a particle at a specific position and time, it is considered complete.
Yes, a wave function can change over time. This is known as wave function evolution and is described by the Schrödinger equation. As a particle interacts with its environment, its wave function may change to reflect its new state.
