How Do Electrons Exhibit Standing Wave Behavior in Atomic Orbits?

In summary: So the electron really does not have a specific direction it is traveling in. It is only moving around the nucleus in a way that creates a wave. However, because we consider the electron as a particle, we can use the wave equation to describe its behavior. The equation says that the momentum of the electron is quantized, in other words, it can only have a certain amount of momentum. And the momentum is proportional to the square of the velocity. So, if the electron has a higher velocity, it has more momentum. However, the electron does not always have a high velocity. In fact, the Bohr model says that the electron has an angular momentum. Angular momentum is

Could anyone please push to the right direction...

Bohr's model of Atom. Energy quantized. Angular momentum. - I understand that
Standing waves - know what it is.

But, when it come to the question why electrons being always accelerated don't radiate, I have a problem.

It says that, the behavior of an electron should be described as a standing wave.

Ok, according to De Broglie, every particle with velocity behave as a wave, but as far as I know, to have a standing wave you have to have basically 2 waves which propagate in opposite directions. Like if one wave reflects from somewhere and goes opposite direction for instance.

But in case of an electron, which flies one direction, we basically have only 1 wave which propagates one direction, means there is nothing which would compensate this wave.

How come that we consider behavior of an electron on an orbital as a standing wave if it flies one direction?

I understand if it would be infinite number of electrons on an orbital, then basically those electrons which are on the upper side of an atom, would compensate those electrons which are on the bottom side, but we have just one electron.

Question: how come that we consider behavior of an electron as a standing wave?

In the Bohr model of the atom, the electron can be pictured as if you were doing a particle in the box calculation where the circumference of the orbit is analogous to the box length. In it, the electron is flying around the nucleus in a semi classical way.

However, in the more general case, DO NOT think of the electron as flying around the nucleus. The wave is a spherical function in the schrodinger equation. not a circular standing wave. In fact, its not really wavy at all. It only has superposition properties like a wave.

What are De Broglie electron waves?

De Broglie electron waves, also known as matter waves, are a concept in quantum mechanics proposed by Louis de Broglie in 1924. They suggest that particles, such as electrons, have both particle-like and wave-like properties.

What is the significance of De Broglie electron waves?

The concept of De Broglie electron waves helped to bridge the gap between classical and quantum mechanics, as it explains the wave-like behavior of particles such as electrons. It also led to the development of wave mechanics, which is a fundamental principle in quantum mechanics.

How are De Broglie electron waves different from classical waves?

Classical waves, such as sound waves, require a medium to propagate, while De Broglie electron waves do not. They are also associated with individual particles, rather than a collective disturbance like classical waves. Additionally, the wavelength of De Broglie electron waves is inversely proportional to the particle's momentum, unlike classical waves where the wavelength is determined by the properties of the medium.

Can De Broglie electron waves be observed?

While De Broglie electron waves cannot be directly observed, their effects can be observed through various experiments, such as the double-slit experiment. This experiment shows the interference pattern created by electrons passing through two slits, which can only be explained by the wave-like behavior of particles.

What are the practical applications of De Broglie electron waves?

De Broglie electron waves have many practical applications, particularly in the field of electron microscopy. They are also used in electron diffraction techniques, which allow scientists to study the structure of materials at the atomic level. Additionally, the concept of matter waves has led to the development of various technologies, such as electron microscopes and particle accelerators.
