Question

Quizplus · Accepted Answer

The probability of finding a particle in a given small region of space in quantum mechanics is proportional to the square of the magnitude of its wave function, according to the Born rule. This is a fundamental principle of quantum mechanics that relates the wave function to probabilities or probability densities.
