How do you find amplitude and probability?
ΨS (n)Ψn(x) = Probability amplitude of observing the particle at slit n given that it originated from the source S. × Probability amplitude of observing the particle at x given that it originated from slit n.
What is probability amplitude function?
In quantum mechanics, a probability amplitude is a complex-valued function that describes an uncertain or unknown quantity. For example, each particle has a probability amplitude describing its position. This amplitude is the wave function, expressed as a function of position.
Why is probability amplitude squared?
Squaring the amplitude, rather Ψ∗Ψ=|Ψ|2 is one way to ensure that you get real-valued probabilities, which is also related to the fact that according to Sturm-Liouville theory (of which the Schrodinger equation is of such a form), the S-L operator yields real eigenvalues, and so on...
What is the difference between probability and probability amplitude?
The phrase probability amplitude is used to describe any wavefunction component, i.e., a quantity which has to be absolute-squared to obtain a probability or a probability density. Thus, for one of our discrete cases, cn would be a probability amplitude, and |cn|2 is a probability.
