i found the answer..
damn, i lost one piece of my note.. no wonder i was lost.
so, what i did i just used bending factor to get the radii.
i'll try to post up the answer then i got back home
thanks
Homework Statement
- single lens
- f=50cm
- refractive index n=1.53
- if object placed 70cm, find the radii of curvature for the two surfaces of the lens which would minimise spehrical aberrationHomework Equations
what i got from my notes
refraction at a spherical surface...
