Question

Explain what happens to the iris and the pupil when you walk into a dark room and turn on a
bright light​

Answer 1

Answer:

Explanation:

If you're in a dark room and turn on bright lights, your pupils constrict to reduce the amount of light. The opposite happens if you walk from bright sunshine into a darkened room. Your pupils dilate to allow more light in so you can see better in your new surroundings.

Answer 2

Explaination about iris and pupil is as follows-

• Iris is a muscular part of eye that controls the size of pupil.
• On walking into dark room from bright light, there is change in the size by dilating or expanding pupil. This is done to get better view in less light or dark room.
• Turning on bright light will now cause the constriction of pupil to limit the amount of light entering the eye.
