Why are we not able to see immediately after we enter a darkened cinema hall?
Answers
Answer:
When we enter a darkened cinema hall from bright sunshine, at first we cannot see anything clearly. After a short time our vision improves. This is because in bright sunshine the pupil of our eye is small and when we just enter the darkened room very little light enters our eye due to which we cannot see properly...
Answer:
We are not able to see because as we enter from a light coloured area to a dark place as it takes time for our iris to set the size of pupil.
When we are in lighted area Size of a pupil is small so that only some amount of light enters our eyes but as we enter into a dark area we need large amount of light to enter in our eyes so , the pupil’s size need to be increased . And this process of increasing the size of pupil takes time so we are not able to view objects clearly immediately .
