Yes, it is so.

Explanation:

Yes, it is so. Power is #100cm.# divided by focal length in centimeters. Focal length of a converging i.e. convex lens is considered positive and focal length of a diverging lens i.e. concave lens is negative.

Therefore power of a convex lens e is positive and that of a concave lens e is negative.

Hence, if power is negative this means focal length is negative and we have a diverging lens.
