Revisit the double-slit experiment of Example Problem 171 Using the same geometry and relative uncertainty in themomentum, what electron momentum would give a position uncertainty of 250 x 10-10 m? What is the ratio of thewavelength and the slit spacing for this momentum? Would you expect a pronounced diffraction effect for thiswavelength?
