ANSWERS TO QUESTIONS
Q41.1
A particle’s wave function represents its state, containing all the
information there is about its location and motion. The squared
absolute value of its wave function tells where we would
classically think of the particle as a spending most its time.

is the probability distribution function for the position of the
particle.
Q41.2
The motion of the quantum particle does not consist of moving
through successive points. The particle has no definite position.
It can sometimes be found on one side of a node and
sometimes on the other side, but never at the node itself. There
is no contradiction here, for the quantum particle is moving as
