Assume that the double-slit experiment could be carried out with electrons using a slit spacing of b= 10.0 . To be able to observe diffraction, we choose lamda=b , and because diffraction requires reasonably monochromatic radiation, we choose (delta P)/P= 0.0100.

Question

Assume that the double-slit experiment could be carried out with electrons using a slit spacing of b= 10.0 . To be able to observe diffraction, we choose  lamda=b , and because diffraction requires reasonably monochromatic radiation, we choose  (delta P)/P= 0.0100.

Part A
What electron momentum would give a position uncertainty of 2.47×10−10m?
Part B
What is the ratio of the wavelength and the slit spacing for this momentum?
