calculate the first six diffraction angles(2?) expected from BCC Fe if the x-ray wavelength is 0.1542 nm (Cu K? radiation). Fe radius:0.124 nm.For cubic crystal d hkl= a? h +k 2 +l22 Bragg’s equation is (n = 1) ?=2 d hkl sin ?hkl = 2 a sin ?hkl ?h + k + l2 2 2 ?,sin ?hkl = ?? h2+ k 2 +l22a ?0.1542nm==0.62182 a 2…
