Thermographic → It is formed from "thermo-" (from Greek "thermos", meaning heat) and "graphic" (from Greek "graphia", meaning writing or recording). The word "thermographic" refers to the recording or representation of heat.
Think of 'heat' ('thermo-') being 'recorded' ('graphic') — that's what thermographic means.
