Physics

Give the MKS units for the following quantities.
Power of lens.


ANSWER

Dioptre.


SOLUTION
The dioptre is the unit of measure for the refractive power of a lens. The power of a lens is defined as the reciprocal of its focal length in meters, or $$D = \dfrac 1f$$, where $$D$$ is the power in diopters and $$f$$ is the focal length in meters.
