Determining the Focal Length and Optical Power of a Lens

To determine the focal length of a lens with an optical power of 2 diopters, we can use the formula:

Focal Length (in meters) = 1 / Optical Power (in diopters)

Using this formula, we can calculate the focal length as follows:

Focal Length = 1 / 2 = 0.5 meters

So, the focal length of the lens with an optical power of 2 diopters is 0.5 meters.
