GENERAL KNOWLEDGE

Detailed explanation-1: -By presenting a sequence of still images in quick enough succession, the viewer interprets them as a continuous moving image. This is the same principle that enables live action film making and projection to work. Film theorists often refer to this illusion of movement as the persistence of vision.

Detailed explanation-2: -It is due to the persistence of vision that we are able to see movie pictures in a cinema hall. The pictures in the form of a long film are projected on the screen at a rate of about 24 pictures per second.

Detailed explanation-3: -This property is used in cinematography as the projector shows us 24 images per second and thus our eyes is not able to determine each of the images separately as till the first image is on retina second is image is shown and thus our eyes get mistaken to see a moving picture instead of 2 pictures separately.
