The distance between a camera lens and the detector in a particular camera is 5.5 cm. If this lens is focused on an object that is very far away, what is the focal length of the lens?
Homework Answers
If the object is very-very far away, then its image is formed at focal point of lens.
Since here image is being formed at 5.5 cm.
Thus,Focal Length of lens = 5.5 cm
