Question: A biconvex glass (n = 1.70) thin lens is to have a +35-cm focal length. If the radius of curvature of each surface is measured to be the same, what must it be? Give your answer in cm to two decimal places.
My answer:
I used this equation 1/f=(n-1)*(1/r1+1/r2), I got an answer 50cm. Am I right or I missing somthings? still doubt
