Answer 1

When you alternate two similar photos, they appear to be moving.

Step-by-step explanation:

When you alternate two photos that are similar, they appear to be moving. This effect is known as the persistence of vision, where the human eye retains an image for a fraction of a second even after it has disappeared. When photos are alternated quickly, like in a flip book, our brain interprets the sequence of images as continuous motion.
