Answer 2

Explanation:

Power of a lens is the ability/tendency of lenses to converge or diverge light rays after refraction.

convergence or divergence depends on the nature of the lens.

its formula is P=1/f (in metres)

f is the focal length in metres.

it's unit is dioptre or simply D.

you can also write it as m^(-1) read metre inverse if you are feeling lazy
