# 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:124 nm.

calculate the first six diffraction angles(2θ) expected from BCC Fe if the x-ray wavelength is 0.1542 nm (Cu Kα radiation). Fe radius:0.124 nm.

For cubic crystal d hkl= a√ h +k 2 +l22 Bragg’s equation is (n = 1) λ=2 d hkl sin θhkl = 2 a sin θhkl √h + k + l2 2 2 ∨,sin θhkl = λ√ h2+ k 2 +l22a λ0.1542nm==0.62182 a 2…
