A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvature with magnitudes of |r1|=10cm and |r2|=15cm. The lens is made of glass with index of refraction nglass=1. 5. We will employ the convention that r1 refers to the radius of curvature of the surface through which light will enter the lens, and r2 refers to the radius of curvature of the surface from which light will exit the lens.

Keep your choice of a major there is probably no single correct choice.
