Is this lens converging or diverging? converging Odiverging Submit Part B Request Answer What is the focal length of of this lens in air (index of refraction for air is nair = 1)? Express your answer in centimeters to two significant figures or as a fraction. View Available Hint(s) [5] VO Submit ? cm H 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 |R|= 10 cm and |R| = 15 cm. The lens is made of glass with index of refraction nglass 1.5. We will employ the convention that R refers to the radius of curvature of the surface through which light will enter the lens, and R refers to the radius of curvature of the surface from which light will exit the lens.
