Lens formula is
1/f = 1/v - 1/u
And to calculate power of lens
P = 1/f
1/f = 1/v - 1/u
And to calculate power of lens
P = 1/f

Lens Formula:-
=1/u+1/v=1/f
Power of lens is the ability of thelens to converge the rays of light falling on it.
Definition: The powerof a lens is the reciprocal of its focal length in meters.
When, f = 1 m, P = 1/f = 1/1 = 1 dioptre.
1 dioptre is the power of a lenswhose focal length is 1 meter.
