|1.||Sometimes shortened to: strobe an instrument producing a flashing light, the frequency of which can be synchronized with some multiple of the frequency of rotation, vibration, or operation of an object, etc, making it appear stationary. It is used to determine speeds of rotation or vibration, or to adjust objects or parts|

|strobe (strōb) Pronunciation Key
A lamp that produces very short, intense flashes of light by means of an electric discharge in a gas. The ability of strobe lights to "freeze" the motion of rapidly moving objects by making them visible for only a fraction of a second makes them very useful in photography and in measuring vibration and other types of high-speed motion.
|stroboscope (strō'bə-skōp') Pronunciation Key
Any of various instruments used to observe moving objects by making them appear stationary, especially with pulsed illumination or mechanical devices that intermittently interrupt observation.
