Bragg's Law
Bragg's Law describes how X-rays scatter off the layers of atoms in a crystal. When X-rays hit a crystal, they can reflect off these layers at specific angles, creating patterns that can be measured. The law is expressed as \(n\lambda = 2d\sin(\theta)\), where \(n\) is an integer, \(\lambda\) is the wavelength of the X-ray, \(d\) is the distance between the crystal layers, and \(\theta\) is the angle of reflection. This relationship helps scientists determine the structure of materials at the atomic level, aiding in fields like chemistry and materials science.

Bragg's Law is a scientific principle that helps us understand how X-rays scatter off the layers of atoms in crystals. It states that constructive interference occurs when X-rays hit the crystal at specific angles, allowing us to determine the arrangement of atoms within the crystal. The law is expressed mathematically as \( n\lambda = 2d \sin(\theta) \), where \( n \) is an integer, \( \lambda \) is the wavelength of the X-rays, \( d \) is the distance between atomic layers, and \( \theta \) is the angle of incidence. This principle is fundamental in crystallography and materials science.
