Question

plss answer these two questions

Answer 1

The amount of light entering the eye is controlled by the muscles of the iris which contract or dilate the pupils. The pupil becomes larger in less light to allow more light to go in and in bright light it constricts or becomes smaller to restrict the amount of light going in.

The generation of two images is not difficult to explain; each of the two mirrors produces an image due to the single reflection of light off one of the mirror faces to an observer's eye. The remaining images are produced as the result of multiple reflections of light off more than one of the faces.

Answer 2

we blink our eyes when they are exposed to bright light suddenly because of the superb reflex control of our eyelids which allow them close automatically when they detect any sudden bright light or any close object to the eye.
