- Homework Statement
- What is the focal length and optical power (in diopters) of the lenses used to produce the following pairs of object and image distances?

do = 1.0 m

di = 0.33 m

- Relevant Equations
- focal length: 1/f = 1/do + 1/di

Power (diopters): 1/fD

1/f = 1/dₒ + 1/dᵢ = 1/1.0 + 1/0.33 = 4.03 m (focal length)

Power: 1/4.03 m or 0.248 (0.25)

*around to the2 decimal points? or leave it as a fraction?

((Did I do this correctly? I am not sure if this is correct and is it okay to be in meters not centimeters?))

Please let me know!
