How does a fluorescent light produce a stroboscopic effect?

Fluorescent lights can produce a stroboscopic effect primarily because they flash on and off at a frequency that can be perceptible to the human eye, often corresponding to the frequency of the alternating current (AC) supply, which is typically 50 or 60 Hz in many regions. When this light flickers at a certain frequency, it can create the illusion of strobing, especially in conditions where movement is present, such as in dance clubs or while shooting video.

The stroboscopic effect is noticeable when fluorescent lights operate in a way that they cycle through their on-off states rapidly, leading to the visual perception of intermittency in the illumination rather than a smooth, steady light output. This effect is particularly pronounced at utility supply frequencies, and the average human eye can perceive flicker at frequencies below around 60 Hz, which can cause objects to appear to jump or freeze in place when they are moving quickly.

The other options do not correctly describe how a fluorescent light produces a stroboscopic effect. While a high-frequency transformer is involved in some types of fluorescent lighting systems to mitigate flicker by delivering a higher frequency supply, this does not directly lead to a stroboscopic effect. Continuous light without flicker would eliminate the st
