When Miles and Mandi leave the bright lobby and enter the movie theater they cannot tell where the empty seats are. Explain why this occurs and describe the process through which they will gradually be able to see
What will be an ideal response?
Answer: A good answer will include the following key points.
• They cannot see because their environment has turned from bright to dim, all of a sudden, not leaving enough time for the rods and cones in the retina to adjust to the change.
• Chemical changes occur in the rods and cones to allow us to adjust to the dark.
• The cones adjust quickly, within about 10 minutes, but never become very sensitive.
• It takes the rods about 20 minutes or more to adjust, but ultimately they are much more sensitive. This process is called dark adaptation.
• Miles and Mandi will be able to see clearly after about 20 minutes from entering the movie theater.
