What is Bragg's equation?

Answer 1

The fundamental equation which gives a simple relation among the wavelength of the X-rays, the inter planar distance in the crystal and the angle of reflection, is known as the Bragg's equation.

2dsin θ = n λ

Some applications of Bragg's equation are:

1. Structures of solids are determined by X-ray diffraction method.
2. Structures of complex substances such as proteins and nucleic acids are also determined by this method.

Answer 2

Bragg's equation is a fundamental law in X-ray crystallography that relates the angle of incidence of X-rays on a crystal to the resulting constructive interference of the diffracted X-rays. It is represented as n*λ = 2d*sin(θ), where n is an integer, λ is the wavelength of X-rays, d is the atomic spacing in the crystal lattice, and θ is the angle of diffraction.
