Answer 1

Persistence of vision refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films.

Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye.[2] The illusion has also been described as "retinal persistence",[3] "persistence of impressions"[4], simply "persistence" and other variations.
