Refraction takes place at a convex spherical boundary separating air-glass medium. For the image to be real, the object distance `(mu_(g) = 3//2)`
Note Object lying in the glass.
A. should be greater than three times the radius of curvature of the refracting surface
B. should be greater than two times the radius of curvature of the refracting surface
C. should be greater than the radius of curvature of the refracting surface.
D. is independent of the radius of curvature of the refracting surface
