[QUOTE="crystal1001, post: 6264761, member: 668562"] [B]Homework Statement:[/B] 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 [B]Relevant Equations:[/B] 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! [/QUOTE]
