The image formed on the retina persists for aboutof a second. This means that if you are shown still pictures of a moving object at a rate faster than 16 seconds, then the object will appear to be moving. This is because, the image of a picture stays on your retina for of a second and you will not be able to recognize the time taken to change these pictures.
