In the lens maker formula, no use of angle of incidence is there.So is it nt of angle ?

lens maker form. for spherical surface= (r.i./v)-(ri2/u)=(ri1-ri2)/R

ri=refractive index

why will u use the angle of incidence here .... its simply distance problems ... object distance and image distance with focal length given ... lens maker formula ultimately gives you the focal length of combination of lenses as a single lens

the lens having the radii of curvature r1 & r2 focal length can be given by{p=1/f=(2n1-1)(1/r1-1/r2)}hence lens maker formula does not require angle of incidence
