2.5 Show that ekx is an eigenfunction of the operator dh What is the eigenvalue? dan Exercise 2 2.7 Assume that the double-slit experiment could be carried out with electrons using a slit spacing of b = 10.0 nm. To be able to observe diffraction, we choose 1 = b, and because diffraction requires reasonably monochromatic radiation, we choose Ap/p = 0.0100. Show that with these parameters, the uncertainty in the position of the electron is greater than the slit spacing b
