The focal length of the lens is 50 cm. What is its optical power?
| January 15, 2021 | education
The optical power of a lens can be calculated using the formula:
D = 1 / F, where D is the optical power of the lens (diopters), F is the focal length of the lens (F = 50 cm = 0.5 m).
Let’s calculate the optical power of the lens:
D = 1 / F = 1 / 0.5 = 2 diopters.
Answer: The optical power of the lens is 2 diopters.
