Question

A series of fast moving still pictures can create an illusion of movement because
(1) the eye can focus on very rapidly changing pictures.
(2) eye is quicker than the brain.
(3) eye can seqarate two images only when the interval of separation between them is one-tenth of a second.
(4) the optical cortex can see through the rapidly moving images.

Answer 1

answer is (3) eye can separate two images only when the interval of separation between them is one-tenth of a second.

Answer 2

A series of fast-moving still pictures can create an illusion of movement because  the eye can separate two images only when the interval of separation between them is one-tenth of a second (Option - 3)

• This phenomenon is called Persistence of Vision.
• An eye can distinguish between 2 images only when shown at an interval of one-tenth of a second.
• If still images are shown at a faster speed, they move quickly in less than one-tenth second, this gives an illusion of movement.
• therefore, the eye can differentiate and perceive much more faster than the brain,
