Question

define the terms in the equation p=1/f(fin meters).​

Answer 1

Explanation:

Answer: When f = 1 meter, P = 1F = 1/ 1 = 1 dioptre. Hence, one dioptre is the power of a lens of focal length one meter. When f is in 1 cm, P = 1F / 100 = 100/ f.

hope it helps dear

Answer 2

Answer:

It is the Reciprocal of Focal Length taken in m. Power of lens = 1/Focal Length. P = 1/f. When Focal Length is Measured in meter (m) Power is Measured in Dioptre (D) .
