A FCC crystal with a lattice parameter of 0.3615 nm is used to measure the wavelength of monochromatic x-rays. The Bragg angle (θ) for the reflection from (111) planes is 21.68°. The wavelength of x-rays (in nm rounded off to three decimal places is )________.
nλ = 2d sinΘ d = a/ (h2 +k2 +l2 )1/2 λ = 0.154 nm
nλ = 2d sinΘ
d = a/ (h2 +k2 +l2 )1/2
λ = 0.154 nm
