Difference Between X-ray Diffraction and X-ray Fluorescence

Here’s a concise comparison chart for X-ray Diffraction (XRD) and X-ray Fluorescence (XRF):

How does X-ray Diffraction and X-ray Fluorescence work?

(XRD):

Imagine shining a super-powered flashlight (X-rays) on a small castle constructed from building blocks (crystals). When the light hits the castle it scatters in many directions, forming an image.

Scientists make use of this pattern, similar to shadows, to determine the manner in which each of the blocks is placed within the castle. It’s similar to studying patterns of reflections in light to comprehend the structure of tiny objects, like particles or crystals.
