Question

Quizplus · Accepted Answer

Persistence of vision is the best explanation for the trail of light left behind by the sparkler. This phenomena occurs because our visual system retains an image for a brief period of time even after the stimulus has been removed. The persistent image of the sparkler creates the impression of a trail of light as it moves through the air.
