Question

The size of the pupil becomes ______ when you see in dim light.

Answer 1

The size of the pupil becomes large when you see in dim light.

Explanation:

In dim light, the amount of light entering the eye is very little. To increase the amount of light, the pupil expands. Behind the cornea, we find a dark, muscular structure called the iris. In the iris, there is a small opening called the pupil, and the iris controls its size.
