Question

Quizplus · Accepted Answer

The Stern and Gerlach experiment demonstrated the concept of space quantisation or the quantisation of angular momentum of atomic particles in space. It showed that the magnetic moment of a silver atom can be aligned only in certain discrete directions when passing through a non-uniform magnetic field, indicating that the angular momentum of the particle is quantised. This discovery was foundational for the development of quantum mechanics. The other answer choices are not relevant to this experiment.
