Question

How can you say that the ability of a lens to converge or diverge light rays depends on its focal length?​

Answer 1

Answer:

The ability of a lens to converge or diverge light rays depends on the focal length of the lens. If the focal length of the lens is small, then the focus of the lens lies nearer to the lens and thus the lens converges or diverges the incident rays nearer to the lens and vice-versa.

Answer 2

Answer:

Yes we can say that the ability of a lens to converge or diverge light rays depends upon it's focal length because the image formation through lens is dependent upon it's focal lens
