IPA: /ˌʌltrəˈmaɪkrəˌskoʊp/
KK: /ˈʌltrəˌmaɪkroʊskoʊp/
A type of microscope that uses strong light to see very tiny objects that cannot be seen with a regular microscope.
The scientist used an ultramicroscope to observe the behavior of colloidal particles.
Ultramicroscope → It is formed from "ultra-" (meaning beyond) and "microscopium" (from Greek "mikros" meaning small and "skopein" meaning to look or examine). The word refers to an instrument that allows one to look beyond the small, enabling the observation of objects that are too small to be seen with a regular microscope.
Think of looking 'beyond' ('ultra-') the 'small' ('micros') to examine things that are too tiny for a regular microscope.
