Answer 1

`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")`
