Probability density refers to the likelihood per unit volume or space for finding a particle at any given point in space. It is derived from the square magnitude of the wave function.
congrats on reading the definition of Probability Density. now let's actually learn it.
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.
