Answer
1 / focal length (f)
here's the solution to your physics problem:
The power of a lens is the reciprocal of its focal length in meters. Formula: Power (P) = 1 / focal length (f)
Given: Focal length (f) = 20 cm
Step 1: Convert the focal length from centimeters to meters. f = 20 cm = 20 / 100 m = 0.20 m
Step 2: Calculate the power of the lens using the formula. P = 1 / f P = 1 / 0.20 m P = 5.0 D
The power of the lens is 5.0 Diopters (D).
