We have lens makers formula that gives focal length of lens in terms of refractive index of material of lens and radii of curvature of lens.

Given lens made up of materials of two different refractive index can be treated as two different lenses each having its respective refractive index.

Hence we get two focal length . Image of distant object will form at two focal point . Hence we get two images
