A free electron in a total vacuum

In summary, the behavior of a free electron released in a total vacuum would be affected by the uncertainty principle and its initial conditions. It is impossible to place the electron at rest at the exact center of a sphere, and it would interact with electromagnetic waves in the vacuum. Its behavior would not be completely random, but rather influenced by these factors.

If you were to release a free electron in a total vacuum what would its behavior be?

Say you released it from the center of a sphere with a surface capable of detecting the electron when it comes in contact. Wouldn't you be able to calculate the speed and direction of the electron by the time it took to get from the center to where ever it connected?

Or does it just wiggle around randomly through space?

Does the uncertainty principle apply only to electrons in orbit?

Thanks,
Eric

No, but it does apply to your initial conditions. You cannot place the electron in the exact center of the sphere, exactly at rest.

Exactly like Bill said, the electron could never truly be placed within the centre of the sphere at rest.

On the behavior that the electron would be inhibiting, this is indeed a tricky question. Though if you were to put an electron inside of a total vacuum the electron would interact with the photons from the electromagnetic waves that exist within the vacuum.
 

1. What is a free electron in a total vacuum?

A free electron in a total vacuum refers to an electron that is not bound to an atom or molecule and is existing in a completely empty space with no other particles or matter present.

2. How does a free electron behave in a total vacuum?

A free electron in a total vacuum behaves according to the laws of quantum mechanics, meaning it can exhibit both wave-like and particle-like properties. It also has the ability to move freely without any resistance or collisions from other particles.

3. What is the significance of studying free electrons in a total vacuum?

Studying free electrons in a total vacuum can provide valuable insights into the fundamental principles of quantum mechanics and the behavior of subatomic particles. It also has practical applications in fields such as electronics and materials science.

4. Can a free electron in a total vacuum exist in real life?

Yes, a free electron in a total vacuum can exist in real life, although it is a highly controlled and rare state. In everyday conditions, electrons are typically bound to atoms or molecules and are not freely floating in a vacuum.

5. How is a free electron in a total vacuum different from an electron in a material or gas?

A free electron in a total vacuum is not affected by any external forces or interactions, while an electron in a material or gas can experience collisions and interactions with other particles. Additionally, a free electron in a total vacuum has a higher energy level compared to an electron in a material or gas due to the absence of any surrounding atoms or molecules.
