What does it mean to observe an electron?

observer effect
In science, the term observer effect means that the act of observing will influence the phenomenon being observed. For example, for us to “see” an electron, a photon must first interact with it, and this interaction will change the path of that electron.

What does it mean to observe in physics?

In physics, the observer effect is the disturbance of an observed system by the act of observation. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner. While the effects of observation are often negligible, the object still experiences a change.

How can we observe an electron?

How do we observe an electron? – Physics Stack Exchange.

What does observation mean in quantum physics?

A system is said to be observed if a measurement of one of the observables of the system has been made by a measurement apparatus that undergoes quantum decoherence . The quantum eraser experiment illustrates that, provided decoherence has not taken place, measurement-like interactions can be reversed.

Why does observing an electron change it?

In other words, when under observation, electrons are being “forced” to behave like particles and not like waves. The quantum “observer’s” capacity to detect electrons could be altered by changing its electrical conductivity, or the strength of the current passing through it.

Why do electrons move differently when observed?

Is it possible to observe an electron?

If indeed Quantum Mechanics describes how the world “really works,” then the concept of observing an electron may actually be impossible due to the statistical behaviors of quantum waveform collapse. Nothing is observed without some physical process ‘performing’ the observation.

Can the position of an electron be observed instantaneously?

While it can be observed instantaneously, it cannot be determined both where it is and its velocity. The speed of an electron can be observed, but not with knowing its position. The position of an electron can be observed, but not with knowing its velocity.

Can you tell the position of an electron without its velocity?

The position of an electron can be observed, but not with knowing its velocity. The often shown example of this in engineering and physics classes in the image of an arrow in the forest. You can clearly see where it is, but from an image of the arrow, you cannot tell how fast it is going.

What is the extent of an electron?

According to the Standard Model, the electron has no extent; a radius of zero. As such, such a particle could never be observed (as it is not really there…) but only indirectly observed by, for example, the effect of its electric field on other particles or objects.
