|
Answer» Wow thanks?? Aur bada ans. Chahiye kya...???? When the eye look at a nearby objects the ciliary muscle of the eye contract. .the contracted ciliary muscle make the suspensory ligaments loose and so suspensory ligaments stop pulling the eye lens ...the thick eye lens has small focal length but have a large converging power and so it converge the light rays coming from the object. .and form image on the retina When the eye is looking at a distant object then the ciliary muscle of the eye area fully relaxed.the relaxed ciliary muscles of the eye pull the suspensory ligaments attached to the eye lens tightly. the suspensory ligaments in turn pulls the eye lens due to which eye lens s gets stretched and becomes thin ...and the things eye lens has large focal length and thus converge the light rays coming from the object at retina and forms image Mein dekhi hun...But mujhe thoda bada answer chahiye because ye 3 marks q. Hai Phy...books me dekho mil jayenge Anything more to add? In short this is have answered And thereby forming image on the retina When the focus nearby objects the ciliary muscle contract and when eye focus distant object. ..it relax and expand |
