Question

Please show me how I prove the formula. Can you show me themore prosess ? there is too much omission.. I think the solution has not completed because there is noanswer for (b). (b) calculate the atomic spacing in a crystal that hasconsecutive diffraction macima at =24.1 and =54.9 for100 eV electrons. I want to see the answer as soos as possible.

Explanation / Answer

the condition for maxima in the interference pattern at theangle bright is d * sinbright= m * or d = (m * /sinbright) the atomic spacing is a = [(m2 * /sin2bright) - (m1 */sin1bright)] or a = * [(m2/sin2bright) -(m1/sin1bright)] ------------(1) 2bright= 54.9o and1bright= 24.1o We know that E = (h * c/) or = (h * c/E) -------------(2) h = 6.63 * 10^-34 J-s c = 3 * 10^8 m/s E = 100 eV = 100 * 1.6 * 10^-19 J = 1.6 * 10^-17 J substituting the value of from (2) to (1) we get thevalue of a
