Dear student
Pls. post each query individually.
The impression of an image on the retina of the eye for some time after its withdrawl is known as persistence of vision. The impression on human eye lasts for 1/16 th of a second.
This property is used in cinematography. Successive images at the rate of 16 per second of the same scene give the impression of continuity.
Hope this helps.
