Question

Define Power of Lens !​

Answer 1

Answer:

Power of lens is the ability of the lens to converge the rays of light falling on it.

It can also be defined as P=1/f where f is the focal length.

S.I. unit of power is D(Dioptre).

It is represented by letter 'P'.

Answer 2

Here is your answer mate !!

______________________

•Power of Lens is its capacity to converge/diverge rays falling on it.

•Quantitatively, Power of a lens is the reciprocal of the focal length of the lens.

•P(Dioptre) = 1/f(in m)

•SI unit :- When f is measured in metre the unit of power is Dioptri(D).
