Dear student
Please find your answer below to the second question:

When we enter a dim room,our pupil is smaller due to abundance of light .But in dim room we require more amount of light to see nearby objects and it takes sometime for the regulation of eye of pupil.So,it takes sometime to see objects in dim room.

Please post different questions in separate thread.
