  • B. is quicker than the brain
  • C. can see 2 images separated only if the interval betwen seeing them is more than one-tenth of a second
  • D. can shut out some of the light

  • Correct Answer
  • can see 2 images separated only if the interval betwen seeing them is more than one-tenth of a second 

    Explanation

    The eye can see images separately only if they are exhibited at an interval of more than 1/10 of a second. In the case of a movie, the still pictures come one after the other at less than this minimum interval. So we do not see them separately but only as a continuous moving picture.
