Question

The sensation of seeing an object remains for about _____ of a second after the object is removed from the view.

• A. $\frac{1}{12}$
• B. $\frac{1}{16}$
• C. $\frac{1}{8}$
• D. $\frac{1}{10}$

Answer 1

The correct option is B

$\frac{1}{16}$

Persistence of vision is the eye’s ability to keep seeing an image of an object for a fraction of a second after the object has disappeared from view. The image of an object stays on our retina even after we’ve stopped looking at it. Our brain actually retains a visual impression for about $\frac{1}{16}th$ of a second.
