Wouldn't any spherical wave impacting the screen extend as far as the length of the screen, hence infinitely distant? AG *
You illustrate my point by immediately abandoning one idealized initial condition by posing another idealization. Engineers and scientists realize they are always calculating with idealizations. Only mathematicians and metaphysicians think the idealizations of their symbol manipulation is reality.
