A double convex lens, made of a material of refractive index μ1, is placed inside two liquids of refractive indices μ2 and μ3, as shown. μ2 > μ1 > μ3. A wide, parallel beam of light is incident on the lens from the left. The lens will give rise to
(a) a single convergent beam
(b) two different convergent beams
(c) two different divergent beams
(d) a convergent and a divergent beam
