Power P of lens in diopters is:
Select the correct option:
Solution
Incorrect! Answer:
P = 1/f(m)
Power (P) is the measure of the convergence or divergence that a lens introduces in the light rays falling on it.
- P=f1 where f is in meters.
- The SI unit is the Diopter (D).
- Converging (convex) lenses have positive power, and diverging (concave) lenses have negative power.
