Morphology

interferometry = interference (semi-transparent) = interfere + metry

The relation between 'interference' (waves overlapping) and '-metry' (measurement) is conceptually clear, but the term is specialized and the suffix '-metry' is not familiar to many learners.

Etymology

Interferometry comes from inter- meaning 'between' and -metry meaning 'measure', and from the idea of 'interference' when two waves meet and change each other. So, interferometry is a way to 'measure' very small distances by watching the patterns made when waves meet.
