Answer to Question #163266 in Optics for Viccy

Question

Explain bragg equation of diffraction.

Answer 1

Bragg's equation of diffraction is expressed as:

$n\lambda =2dsin\theta$

The equation illustrates the reason why the faces of crystals reflect X-ray beams at specific incident angles $\left(\theta ,\lambda \right)$.

The variable $d$ points the distance between atomic layers while the variable $\lambda$ specifically explains the wavelength of incident X-ray beam.

Lastly, $n$ is an integer such as: $1,2,3......$
