What happens to the particle in one dimensional box if length of the box is increased?

If you increase the length of the box, the uncertainty in position is large, thus resulting in a lower uncertainty in momentum, and a lower minimum momentum, and a lower energy.

What happens to electrons when they move to lower energy levels?

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

What affects energy level spacing?

The energy is negative and approaches zero as the quantum number n approaches infinity. We saw that as the potential box gets wider, the energy level spacing gets smaller. Similarly in the hydrogen atom as the energy increases, the Coulomb well gets wider and the energy level spacing gets smaller. Figure 8.3.

What happens to the energy levels for an electron trapped in a one dimensional box as the length of the box increases?

As L increases, En will decrease and the spacing between energy levels will also decrease.

What is the energy of particle in one dimensional box?

The energy of a particle is quantized. This means it can only take on discreet energy values. The lowest possible energy for a particle is NOT zero (even at 0 K). This means the particle always has some kinetic energy.

What is the physical interpretation of the wave function?

The physical meaning of the wave function is an important interpretative problem of quantum mechanics. The standard assumption is that the wave function of an electron is a probability amplitude, and its modulus square gives the probability density of finding the electron in a certain location at a given instant.

Why is the energy of a particle trapped inside a box quantized?

The energy of a particle is quantized. This means it can only take on discrete energy values. The lowest possible energy for a particle is NOT zero (even at 0 K). This means the particle always has some kinetic energy.

Why do the energy levels get closer together as they increase?

Re: Distance between energy levels As the energy levels increase, the pull on the electrons to the nucleus decrease gradually;therefore, they are closer when n=3,4,5…

What happens to the distance between the energy levels as n increases?

Down a group, the number of energy levels (n) increase and the distance is greater between the nucleus and highest-energy electron. The increased distance weakens the nuclear attraction to the outer-most electron, and is easier to remove (requires less energy).

Who discovered quantum world?

German physicist Max Planck publishes his groundbreaking study of the effect of radiation on a “blackbody” substance, and the quantum theory of modern physics is born. Through physical experiments, Planck demonstrated that energy, in certain situations, can exhibit characteristics of physical matter.
