## What is E in Schrodinger equation?

The Schrödinger equation is written Hψ = Eψ, where H is an operator and E is the energy of the system.

## Why is there an I in the Schrodinger equation?

The imaginary constant i appears in the original Schroedinger article (I) for positive values of the energy, which therefore are discarded by Schrödinger, who wants real eigenvalues and requires negative energy.

## What is a wave function write down Schrodinger’s wave equation for a free particle?

The wave function Ψ(x, t) = Aei(kx−ωt) represents a valid solution to the Schrödinger equation. The wave function is referred to as the free wave function as it represents a particle experiencing zero net force (constant V ).

## Is the cat alive or dead?

In simple terms, Schrödinger stated that if you place a cat and something that could kill the cat (a radioactive atom) in a box and sealed it, you would not know if the cat was dead or alive until you opened the box, so that until the box was opened, the cat was (in a sense) both “dead and alive”.

## What is Schrodinger’s law?

In Schrodinger’s imaginary experiment, you place a cat in a box with a tiny bit of radioactive substance. Now, the decay of the radioactive substance is governed by the laws of quantum mechanics. This means that the atom starts in a combined state of “going to decay” and “not going to decay”.

## How did Schrodinger arrive at his equation?

In Schrödinger’s first paper, he used the variation technique along with the Hamiltonian-Jacobi equation (HJ eqn) and a novel expression relating the action to an unknown function (wave function). By doing so he obtained a new differential equation, the Schrödinger equation, to model physical phenomenon.

## How does Schrodinger get his equation?

In their paper, the physicists developed a new way to obtain the Schrödinger equation starting from a mathematical identity using classical statistical mechanics based on the Hamilton-Jacobi equation. In quantum mechanics, both amplitude and phase depend on each other, and this makes the quantum wave equation linear.”

## How does Schrodinger equation work?

The Schrodinger equation is used to find the allowed energy levels of quantum mechanical systems (such as atoms, or transistors). The associated wavefunction gives the probability of finding the particle at a certain position. The solution to this equation is a wave that describes the quantum aspects of a system.

## Did Schrodinger own a cat?

Erwin Schrödinger doesn’t appear to have personally owned a cat. He did however own a dog. His great-aunt owned several cats.

## Why is the cat alive and dead?

Until the box is opened, an observer doesn’t know whether the cat is alive or dead—because the cat’s fate is intrinsically tied to whether or not the atom has decayed and the cat would, as Schrödinger put it, be “living and dead in equal parts” until it is observed.

#### Energy equation physics

What is the formula for energy? The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second. How do you solve for energy in physics? In classical mechanics, kinetic energy (KE) […]
