1 diopter equal 100 c.m.

Its equal to 1 meter or you can say 100 c.m.

1D = 1/f, where f = 100 cm or 1 m.

@Monika.
Value of 1/f =1/100.
So f=100.
Value of 1/f =1/100.
So f=100.

What is Means Diopter:-
-> A dioptre (uk), or diopter (us), is a unit of measurement of the optical power of a lens or curved mirror,
-> which is equal to the reciprocal of the focal length measured in metres.
Slove:-
1/metres For example, a 3-dioptre lens brings parallel rays of light to focus at 1/3 metre.
(Right Answer- 1 Diopter egual 100 cm or 1 m.)
