Intro to Chemistry

Definition

The Bragg equation, $n\lambda = 2d\sin\theta$, describes the condition for constructive interference of X-rays scattered by a crystalline lattice. It relates the wavelength of X-rays to the angle at which they are diffracted and the spacing between crystal planes.

congrats on reading the definition of Bragg equation. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. The Bragg equation is essential for determining crystal structures using X-ray diffraction.
  2. In the equation $n$ is an integer representing the order of the diffraction.
  3. $\lambda$ is the wavelength of the incident X-rays.
  4. $d$ is the distance between atomic layers in a crystal, known as interplanar spacing.
  5. $\theta$ is the angle between the incident X-ray and the scattering plane.
