What does strobe mean?
A strobe is a light or device that produces brief, intense flashes, often at regular intervals. In photography and film, strobe lighting can capture motion in a way that makes movement appear frozen, stepped, or unusually slow. The word can also refer to the visual effect itself, as in “strobe lighting,” and can be used as a verb to describe rapid flashing or movement. Stroboscopic effects rely on the fact that the human eye tends to integrate rapid flashes into a continuous image, so each flash briefly dominates what the viewer sees. The term is consequently associated with nightlife, performances, emergency-warning lights, and visual effects designed to make an audience perceive motion in an unusual way. It is more technical than the general word “flash” and less specific than “stroboscope,” which names the instrument that creates the effect.
A device or light that produces brief, regular flashes, or the effect of such flashing.
"A strobe flashed at the back of the stage as the music began."
The word is especially common in photography, film, performance, and emergency-signal contexts.
To flash rapidly, or to move or be illuminated in rapidly flashing light.
"The camera strobed as it recorded the dancers."
This use is more specialized than the noun and is often found in technical or descriptive contexts.
Use the plural when referring to more than one flashing device or light.
"Several strobes were positioned around the stage."
A strobe freezes motion in the human eye by revealing each instant as a separate flash, turning a moving scene into a sequence of still images.

Etymology of strobe
The word developed in the early 20th century from the scientific terminology surrounding stroboscopic effects. It is connected with Greek strobos, associated with whirling or turning, and with stroboscope, an instrument using regularly timed flashes to study motion. The shorter form “strobe” became established for both the light source and the flashing effect, while “stroboscopic” remained the more technical adjective.
