Question

The persistence of vision of a normal human eye is:

• A. 1/10S
• B. 1/16S
• C. 1/20S

Answer 1

The correct option is B

1/16S

The correct answer is option A

Explanation of the correct option:

1. Persistence is an optical phenomenon in which the brain interprets numerous stationary images as one to generate the appearance of motion.
2. The vision of a normal human eye lasts 1/16 second.
3. Because the human brain and eye can only process 12 images per second roughly, each image gets retained only for 1/16 of a second.

Final answer:

The persistence of vision of a normal human eye is 1/16S.
