"Wave-particle duality" and double-slit experiment

In summary, wave-particle duality is a fundamental concept in quantum mechanics that describes how particles, such as electrons and photons, exhibit both wave-like and particle-like properties. The double-slit experiment demonstrates this duality; when particles are fired at a barrier with two slits, they create an interference pattern characteristic of waves when not observed. However, when measured, they behave like particles, hitting the screen in distinct locations. This experiment illustrates the complexity of quantum behavior, suggesting that the nature of particles can change depending on observation.

Not at the same time, no.
Sorry, your answer refers to the fact that both momentum and position cannot be known at the same time with arbitrary precision, right?
Or are you referring to the fact that both momentum and position cannot be known at the same time in any way?

Just to be sure.
