Answer to Question #198460 in Quantum Mechanics for Marisa

Question

How does the motion of a classical object (like a bowling ball) compare to the motion of a quantum object (like an electron) when passing through two slits?

Answer 1

Classical particles haven't probability nature of motion, vice versa quantum particles. We can't say about a point where quantum particle is. In two slits experiment the main difference between quantum and classical particles is interferention picture on the plane. This picture satisfy the idea of probability law of quantum particles before seporation on slits.
