Question

When all else remains the same, what effect would decreasing the focal length have on a convex lens?

It would cause the lens to produce only real images.
It would cause the lens to produce only virtual images.
It would make the lens stronger. 
It would make the lens weaker.

GPT-5 mini · Answer

It would make the lens stronger.

Explanation: optical power P = 1/f (in meters), so decreasing the focal length f increases the lens' power — it bends rays more (stronger convergence). It does not force images to be only real or only virtual; image type still depends on object distance.
