what is power of lens
Answers
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:
IPower of a lens(P) is defined as the ability of a lens to converge/ diverge the light rays falling on it. It is the reciprocal of focal length of the lens in metre. P=1/f. Its unit is dioptre

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
The ability of a lens to converge/diverge a beam of light rays is expressed in terms of its Power(P). P=1/f. The SI unit of power of lens is Dioptre.It is denoted by the letter "D" SI unit of length is metre(m)
