## 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.
