*I'm not sure. Wouldn't any spherical wave impacting the screen extend as far as the length of the screen, hence infinitely distant?

Suppose I have a wf in one spatial dimension and calculate the probability density at some value of x. Isn't any x acceptable, say for a free particle, implying the wf extends to infinity?
