## What is PSI Schrodinger equation?

Psi stands for the wave function of the system describing the state of the system. If psi is a solution of the time-independent Schrodinger equation, it depicts the state of a system with a specific energy.

## What does the wave function Ψ represent?

Wave Functions. A wave function (Ψ) is a mathematical function that relates the location of an electron at a given point in space (identified by x, y, and z coordinates) to the amplitude of its wave, which corresponds to its energy. Thus each wave function is associated with a particular energy E.

What is the formula of wave function?

The general equation for a moving wave is, Ψ(x,t) = Acos(kx-ωt) (17.1) A is equal to the amplitude. k is multiplied by x to determine the wavelength, and ωt determines where the peak lies.

What do wave functions describe?

wave function, in quantum mechanics, variable quantity that mathematically describes the wave characteristics of a particle. The value of the wave function of a particle at a given point of space and time is related to the likelihood of the particle’s being there at the time.

### What is the difference between psi and psi 2?

Psi (ψ) is used to denote the wave function which has no physical significance. The square of the wave function, Ψ 2, however, does have physical significance.

### Who derived the wave equation?

physicist Leonhard Euler
Swiss mathematician and physicist Leonhard Euler (b. 1707) discovered the wave equation in three space dimensions.

Why is wave function squared?

The deep reason for the interpretation that the square of the wave function gives the probability to find the particle with the energy E_n at a certain position in space, lies simply in the linear structure of quantum theory.

What is a wave function called?

A wave function in quantum physics 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.
