Which of the following equation describes Bragg’s law of diffraction? (Assume that all symbols have their usual meaning.)
Bragg’s law, which describes the constructive interference conditions for θ to be at its strongest: nλ = 2d sinθ
Bragg's Law relates the angle θ (at which there is a maximum in diffracted intensity) to the wavelength of X-rays and the interlayer distance d between the planes of atoms/ions/molecules in the lattice.
Condition for constructive interference (maxima in the reflected).
nλ = 2d sinθ
λ = Wavelength of the X-ray
d = distance of crystal layers
θ = incident angle (the angle between the incident plane and the scattering plane)
