#f = 0.1" m" or 10" cm"#

Explanation:

The power of the lens is measure in diopters and is calculated as follows:

#color(white)(aaaaaaaaaaaaaaaa)color(orange)(P = 1/f#

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

To find the focal length, we would first rearrange the equation to get #"f"# by itself,

  • #P = 1/f#

  • #f = 1/P#

now, plugin

  • #f = 1/10#

  • #f = 0.1" m" or 10" cm"#

#color(blue)("Answer": "focal length" = 0.1" m" or 10" cm")#
