Determine the optical power of the lens D, with its focal value F equal to 50 cm.
| March 2, 2021 | education
Problem data: F (focal value of the lens taken) = 50 cm (in SI F = 0.5 m).
To determine the optical power of the lens taken, use the formula: D = 1 / F.
Let’s calculate: D = 1 / 0.5 = 2 diopters.
Answer: The taken lens has an optical power of 2 diopters.
