Question

Give the relationship between Focal Length,Object Distance,Image Distance.​

Answer 1

Answer:

Explanation:

Starting from a large value, as the object distance decreases (i.e., the object is moved closer to the lens), the image distance increases; meanwhile, the image height increases. ... As the object distance approaches one focal length, the image distance and image height approaches infinity.

Answer 2

let 'f' be the focal length , 'u' be the object distance and 'v' be the image distance

1/v -1/u = 1/f it is called the lens formula

hope it helps u....
