A biconvex lens has two distinct radii of curvature. One face has a radius of curvature of magnitude R1 = 12.3 cm

A biconvex lens has two distinct radii of curvature. One face has a radius of curvature of magnitude R1 = 12.3 cm, and the opposite face has a radius of curvature of magnitude R2 = 17.9 cm. The lens medium has an index of refraction of n = 1.51.


 (a) Calculate the focal length (in cm) of the lens for light incident on the side with radius of curvature R1. 

 (b) Calculate the focal length (in cm) of the lens for light incident on the side with radius of curvature R2.

    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...
