Asked by Jessica
The left face of a biconvex lens has a radius of curvature of magnitude 12.8 cm, and the right face has a radius of curvature of magnitude 17.9 cm. The index of refraction of the glass is 1.45
a) Calculate the focal length of the lens for light incident from the left.
b) After the lens is turned around to interchange the radii of curvature of the two faces, calculate the focal length of the lens for light incident from the left.
