Lens-Maker Formula: A thin double-convex lens is intended to focus the image of an object onto a screen so that the image is life-sized on the screen. The lens has equal-magnitude radii of 83 cm and a refractive index of 1.6. (a) What is the distance d from the image to the screen?(b) What is the total distance L between the object and the image?
A. (a) d = 138 cm
(b) L = 276 cm
B. (a) d = 276 cm
(b) L = 552 cm
C. (a) d = 69 cm
(b) L = 35 cm
D. (a) d = -138 cm
(b) L = -276 cm
