Detailed Solution

The above statement is True.
An imprint of the formation of the image remains on our retina for 1/16th of a second after it forms on the retina, not instantly dissipating. Therefore, if we move our hands more quickly, they will appear to be moving, and we will see a fuzzy image.
The retina contains millions of light-sensitive cells (rods and cones) and other nerve cells that receive visual information and then organize them. The retina sends this information to the brain through the optic nerve, enabling us to see.
In the case of Boojho's experiment, he waved his hand very quickly in front of his eyes, causing his fingers to seem blurry.
