Wave Function:The wave function provides information about the probability distribution of finding a particle in different states, which can be used to calculate probability densities.
Normalization: Normalization refers to adjusting the wave function so that its total probability equals 1. It ensures that all possible outcomes are accounted for.
Quantum Tunneling: Quantum tunneling occurs when a particle passes through a potential barrier even though it does not have enough energy to overcome it classically. Probability density plays a crucial role in understanding this phenomenon.
