In quantum physics, a wave function is a mathematical description of the quantum state of an isolated quantum system. The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurements made on the system can be derived from it. The most common symbols for a wave function are the Greek letters ψ and Ψ (lower-case and capital psi, respectively). WebMar 2, 2016 · As shown in pic.02, the state vector is a set of values that each element is the value of the wave function, e.g. phi (0), phi (0.002), etc. Thus, it can be considered as a constant since every elements will never change Therefore, it can be pulled out from the integral ------------- However, this idea is fail to explain in the observable case. shorelines new hanover county nc https://holistichealersgroup.com
