#f = 0.16" m"#

Explanation:

The Power of a lens is the inverse of the focal length when describing thin lens. It is measured in diopters. Optometrists use power lens to prescribe glasses to patients.

The relationship is seen from the following:

#"Power" = (1/f)#

Where
#f = "focal length (m)"#

#color(white)(---)#

To find the focal length, isolate f, plug in and solve

  • #P = (1/f)#

  • #6 = (1/f)#

  • #f = (1/6)#

  • #f = 0.16" m"#

#"Answer": f = 0.16" m"#
