Question

We will not able to see the things clearly when we came out of a dark room, why? .​

Answer 1

Answer:

We can't see things clearly when we come out of a dark room because when we are in the darkroom, our pupil size becomes bigger in size to collect more light but when we come out of the darkroom, it takes some time for the pupil to reduce in size. We can't see things clearly during this time.

Answer 2

We will not able to see things clearly when we came out of a dark room because of the time taken by the pupils to adjust their size according to the light emitting from the surrounding.

• When we stay inside a dark room, the size of our pupils enlarges. This is to collect more light from the surroundings and help us make out the various objects in the room.
• Similarly, in a room with sufficient light, the size of our pupil decreases, this is to take lesser light as the excess of light will cause much damage to our eyes.

Therefore, when we come out of a dark room,

The pupils take some time to decrease their size to take lesser light. The time interval during which this happens causes us to unable to see things clearly.
