Question

and the first interference maximum lies at an angle of 0.60 urad from the center of the interference pattern. What is the momentum of the incoming electrons? A. 2.2 x 1025 kg-m-s1 B. 6.6x 1025kg-m-s1 C. 8.8 x 1023 kg-ms1 D. 2.2 x 10-23 kg-m-s1 E. 7.4 x 102kgm-s1 F. none of the above.

Answer 1

Position of n^{​​​​​​th} Maxima is Y_{​​​​​​n} = nD$\lambda$/d

Hence angular position of n^{​​​​​​the} Maxima = n$\lambda$/d
