When two converging lenses of equal focal lengths are used together, the effective focal length of the combination is less than the focal length of either individual lens. The power of the lens combination will be:

Correct Answer: A. greater than the power of either individual lens.
Lens power is the reciprocal of the focal length: P = 1/f. If the effective focal length of the lens combination is less than the focal length of either individual lens, then the power of the combination must be greater than the power of either individual lens.
