Question

1. Bragg's law for XRD are :
(1) 2d sin 0 - na
(C) 2d sin = a/n
(B) 2d cos () = na
(D) d sin 0 = na​

Answer 1

● Bragg's law for XRD are: nλ=2d⋅sinθ

• n is an integer determined by the order given,

• λ is the wavelength of x-rays, and moving electrons, protons and neutrons,

• d is the spacing between the planes in the atomic lattice, and

• θ is the angle between the incident ray and the scattering planes.
