How can electrons form a wave?

In summary, electromagnetic waves can travel through empty space using only one particle, unlike air or water waves which require a medium. This is because the electromagnetic field stretches throughout all of space and propagates at a finite speed, similar to a disturbance in an elastic body. The radiation field "detaches" from the charge and continues to propagate independently. This concept is similar to sound waves traveling through a solid by vibrating atoms in lattice sites.

an air wave takes place in volumes of air, water takes place in volumes of water... but u can have an electromagnetic wave go through empty space using only one particle. how does this work? this to me does not seem analogous to the waves that i am used to. does this "wave" instead refer to the electromagnetic charge of the particle or something?

Let's say a charge is accelerating through free space. From one instant of time to the next, the electromagnetic field the charge carries will change at the location of the charge. But the electromagnetic field of the charge stretches throughout all of the space while at the same time being relativistic so its local change from one instant to the next has to propagate out to spatial infinity at some finite speed akin to a disturbance in an elastic body. This propagation is electromagnetic radiation. Scroll down in the following document until you see the section on radiation: http://physics.weber.edu/schroeder/mrr/MRRtalk.html

But keep in mind an important point: the radiation propagates out to spatial infinity independently of the charge in the sense that it "detaches" itself from the charge. The key difference between the near-zone electromagnetic field of the charge and the radiation field is the latter does not die out fast enough by the time it reaches the far-zone ("wave-zone").

This is not unlike the sound waves that propagate throughout the entirety of a solid by means of successive vibrations of atoms in lattice sites when you say disturb the solid by punching it at a single point.

thx i get it now ur description was very helpful
 

1. How can electrons form a wave?

Electrons are particles that carry a negative charge and can behave like waves under certain conditions. This phenomenon is known as wave-particle duality and is explained by quantum mechanics.

2. What causes an electron to act like a wave?

According to the principles of quantum mechanics, particles such as electrons can behave like waves because they do not have a definite position or momentum until they are observed. This is known as the uncertainty principle.

3. How is the wave behavior of electrons measured?

The wave behavior of electrons can be measured through experiments such as the double-slit experiment, where electrons are passed through two slits and create an interference pattern on a screen, similar to how waves behave.

4. Can electrons only form waves in certain materials?

No, electrons can exhibit wave behavior in any material. However, the effect is more noticeable in materials with smaller particles, such as in atoms and subatomic particles.

5. What practical applications does the understanding of electron waves have?

Understanding the wave behavior of electrons is crucial in the development of technologies such as quantum computing and electron microscopy, as well as in our understanding of atomic and subatomic particles.
