Answer» Right option is (a) 2 To explain I WOULD say: The portion of a refracting medium, whose CURVED surface forms the part of a sphere, is known as a SPHERICAL refracting surface. Spherical refracting SURFACES are of TWO types, namely, convex refracting spherical surface and concave refracting spherical surface.
