Hola !!!

Here is your answer ⬇️

_______________________________

Power of lens is the measurement of bending strength of a lens i.e. when a ray is incident on a lens then the degree with which the lens bends the ray is determined by the power of lens .

We can write the formula in the following way

P = 1/focal length .
