The lens shown has radii 21.4 cm and 20.4 cm and is made of a material with index of refraction 1.50. Using the shape of the lens to assign the given radii, calculate the focal length of the lens. Consider the case where 21.4 cm is the left side and 20.4 cm the right side. (What would you get if you reversed the order, ie. flipped the lens so the two sides are switched?)
