Final answer:
A short focal length in a converging lens indicates that the lens has a high power, since the power is the inverse of the focal length.
Step-by-step explanation:
If you have a short focal length converging lens, this means that the power of the lens is high. The power of a lens, represented as P, is directly related to how much it can bend light rays. This relationship is mathematically defined as the inverse of the focal length (f), so a shorter focal length results in a greater power. In equation form, this is expressed as P = 1/f, where the focal length f is measured in meters and power P in diopters (D). A short focal length in a converging lens indicates that the lens has a high power, since the power is the inverse of the focal length.
