Best Answer

Take the reciprocal of the focal length measured in metres.

The optical power of a lens (or mirror) with a focal length on 2.5 metres is 1/2.5 = 0.4 dioptres.

How do you convert from centimeters to diopters?

You take the inverse of centimeters and then multiply by 100. For instance, 40 centimeters converts to 2.50 diopters. The inverse of 40 is 1/40 which equals 0.025 0.025 x 100 = 2.50


What is the power of a convex lens with 10cm focal length?

The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a convex lens with a 10 cm focal length has a power of +10 diopters.


If someone is 3.75 in her left and 4.00 diopters in her right and her friend has 800 and 500 degrees who has worse eyesight and what is the conversion between degrees and diopters?

The person with 4.00 diopters in their right eye has worse eyesight compared to their friend with 500 degrees. The conversion between degrees and diopters is as follows: 1 diopter is equal to 1 / focal length of lens in meters.


When was Farsighted for Two Diopters created?

Farsighted for Two Diopters was created in 1976.


What are diopters?

Diopters are a unit of measurement used to quantify the focusing power of a lens, which is important in optometry and ophthalmology. They indicate how much a lens converges or diverges light. Positive diopters indicate converging lenses (helps nearsightedness), negative diopters indicate diverging lenses (helps farsightedness), and zero diopters indicate no optical power.

What will be the power of convex lens having a focal length is 50 cm?

The power of a lens is given by the formula P = 1/f, where f is the focal length in meters. Converting 50 cm to meters, we get f = 0.5 m. Therefore, the power of a convex lens with a focal length of 50 cm is P = 1/0.5 = 2 diopters.
