In the case of an atom, psi is a function of th. In particular, if psi is a solution of the time-independent Schrodinger equation, it corresponds to a state of a system with a specific energy. This range of quantum number starts from nucleus side with n=1 having the lowest energy level. Answer (1 of 2): Psi stands for the wave function of the system, which describes the state of the system. Postulates of Bohr’s Model of an Atom The energy levels are represented by an integer (n=1, 2, 3…) known as the quantum number.

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. Erwin Schrodinger was one of the key figures in quantum physics, even before his famous 'Schrodinger's Cat' thought experiment.He had created the quantum wave function, which was now the defining equation of motion in the universe, but the problem is that it expressed all motion in the form of a series of probabilitiessomething which goes in direct violation to how most scientists of the. Wave function, in quantum mechanics, variable quantity that mathematically describes the wave characteristics of a particle. What is wave function and its significance? It has a number of important physical applications in quantum mechanics. where U(x) is the potential energy and E represents the system energy. The time independent Schrodinger equation for one dimension is of the form. Now I discovered that the Schrödinger’s equation can also be explained in terms of the present formulation. What is time independent Schrodinger equation? the equation for Einstein’s relativistic energy and Newton’s law of universal gravitation. In the second step, the classical wave equation becomes exactly the Schrödinger equation thanks to the numerical value of the parameter obtained from the identification of the classical momentum with de Broglie momentum of matter waves. The Schrödinger equation is an equation of quantum mechanics: calculated wave functions have discrete, allowed values for electrons bound in atoms and molecules all other values are forbidden. by Schrödinger in the original formulation of his theory. The wave function Ψ is a mathematical expression. The wave function’s symbol is the Greek letter psi, Ψ or ψ. In this equation, h is Planck’s constant, m is the mass of the particle in kg, and v is the velocity of the particle in m/s Particularly, the wavelength (λ) of any moving object is given by: λ=hmv. In 1924, French scientist Louis de Broglie (1892–1987) derived an equation that described the wave nature of any particle. This atomic model is known as the quantum mechanical model of the atom. Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. In 1926 Erwin Schrödinger, an Austrian physicist, took the Bohr atom model one step further. The equation also describes how these waves are influenced by external factors. Schrodinger equation gives us a detailed account of the form of the wave functions or probability waves that control the motion of some smaller particles. What is the importance of Schrodinger wave equation? It uses the concept of energy conservation (Kinetic Energy + Potential Energy = Total Energy) to obtain information about the behavior of an electron bound to a nucleus.

\[ \psi (\theta, \varphi ) = \Theta (\theta ) \Phi (\varphi) \label\): Polar plots in which the distance from the center gives the value of the function \(Y\) for the indicated angle \(\theta\).The Schrödinger equation, sometimes called the Schrödinger wave equation, is a partial differential equation.

We first write the rigid rotor wavefunctions as the product of a theta-function depending only on \(\theta\) and a \(\phi\)-function depending only on \(\varphi\) Only two variables \(\theta\) and \(\varphi\) are required in the rigid rotor model because the bond length, \(r\), is taken to be the constant \(r_0\). To solve the Schrödinger equation for the rigid rotor, we will separate the variables and form single-variable equations that can be solved independently.
