Answer 1

The power of the lens with a focal length of 10 cm is 10 D.

Step-by-step explanation:

The power of a lens with a focal length of 10 cm is represented by the formula P = 1/f, where P is the power measured in diopters (D) and f is the focal length measured in meters. Since the focal length is given as 10 cm, we need to convert it to meters by dividing by 100. Plugging in the values, we have P = 1/(10/100) = 1/0.1 = 10 D. Therefore, the power of the lens is 10 D.
