Electrons are fired through a double slit with a separation distance of 2.5 mm, onto a 5 mm wide screen that is placed 1.5 m behind the double slits. What is the minimum momentum of the electrons such that any diffraction can be seen? Hint: for diffraction to be seen, the m = 1 bright spots must be captured by the screen.
