Question

what is the formula for lens in terms of power​

Answer 1

P=1/f(m)



hope it will help u.......

Answer 2

here is your answer

The ability of the lens to converge and diverge the light rays falling on it is called as the POWER OF LENS

it is represented by P

its unit is dioptre which is measured in meters.

acc. to formula

Power of lens is the reciprocal of focal length in one meter

P = 1/f

if there are more than one power then

P = P1 +P2 +P3
