Question

curvature of lens is directly or inversely proportional to focal length how​

Answer 1

Answer:

curvature of lens is directly proportional to focal length how

Answer 2

Answer:inversely proportional

Explanation:Curvature of eye lens is inversely proportional to the focal length.

If the focal length is more ,it is obvious light rays gonna deviate more and thus lens is thin.

If focal length is less,light rays gonna deviate less and hence the lens becomes thicker i.e. curvature increases.
