IPA: //ˈstroʊbəˌskoʊp//
KK: /ˈstrōbəˌskōp/
A device used to observe moving objects by making them look still, often using flashes of light or mechanical interruptions.
The scientist used a stroboscope to study the motion of the spinning wheel.
Stroboscope → It is formed from "strobos" (from Greek, meaning to turn or twist) and "skopein" (from Greek, meaning to look or examine). The word "stroboscope" refers to an instrument that allows one to look at objects in motion by creating the illusion of stillness through rapid flashes of light.
Imagine looking at something that 'turns' ('strobos') while you 'examine' it ('skopein') — that's how a stroboscope helps you see motion clearly.
