Question

Complete the sentences using geometric terms to describe what happens to a pupil during an eye exam.



When a bright light is shown into an eye, the pupil becomes Question Blank 1 of 6
Answer
in size. In geometry, this is called a Question Blank 2 of 6
Answer
. The pupil's size becomes about Question Blank 3 of 6
Answer
its normal size.



With the eye drops, the pupil becomes Question Blank 4 of 6
Answer
in size, since it has to work harder in the dark to see. In geometry, this is called an Question Blank 5 of 6
Answer
. The pupil's size becomes about Question Blank 6 of 6
Answer
its normal size.

Answer 1

When a bright light is shown into an eye, the pupil becomes smaller in size. In geometry, this is called a contraction (reduction). The pupil's size becomes about half its normal size.

With the eye drops, the pupil becomes larger in size, since it has to work harder in the dark to see. In geometry, this is called a dilation (enlargement). The pupil's size becomes about twice its normal size.
