A tool used to study the arrangement of atoms in materials by analyzing how they scatter radiation, particularly X-rays.
The scientist used a diffractometer to examine the crystal structure of the new material.
Diffractometer → It is formed from "diffract" (from Latin "diffringere", meaning to break apart) and "-ometer" (from Greek "metron", meaning measure). The word refers to an instrument that measures the way waves break apart when they encounter an obstacle or a slit.
Think of waves 'breaking apart' ('diffract') and being 'measured' ('-ometer') — that's what a diffractometer does.
