Question

what happens to the image distance in the normal human eye when we decrease the distance of an object say 10 m to 1 m justify your answer​

Answer 1

There is no change to the image distance in the eye when we increase the distance of an object from the eye. To see closer or distant object clearly, the eyes, due to its ability of accommodation, can increase or decrease focal length of its lens, so that the image is always formed at retina.

Answer 2

Hey dear,

● Answer -
Image distance remains same.

● Explanation -
- Human eye have the ability to adjust focal length of its lens using ciliary muscles. This is called accommodation.
- When object is moved from 10 m to 1 m from eye, our eye changes its focal length so as to form image on retina itself.
- Therefore, when we change object distance within specified limits, image distance still remains same due to ability of accommodation.


Hope this helps you ...
