Meaning or Physical Significance of Wave Function Ψ

The variable quantity which describes de-Broglie wave is called wave function Ψ.

MEANING OR PHYSICAL SIGNIFICANCE OF WAVE FUNCTION Ψ

1. The variable quantity which describes de-Broglie wave is called wave function Ψ.

2. It connects the particle nature and its associated wave nature statistically. 

3. The wave function associated with a moving particle at a particular instant of time and at a particular point in space is related to the probability of finding the particle at that instant and at that point.

4. The probability 0 corresponds to the certainty of not finding the particle and probability 1 corresponds to certainty of finding the particle.


5. The probability of finding a particle at a particular region must be real and positive, but the wave function Ψ is in general a complex quantity.
