Lens which converges incident rays on a single point is

Question

BlackTom AI · Accepted Answer

Question restatement: The prompt asks which lens focuses incident rays to a single point, i.e., which lens converges light.
Option a: convex lens. This is the correct category of lens for convergence; a convex (converging) lens causes parallel rays to refract toward the focal point on the other side.
Option b: concave lens. A concave (diverging) lens spreads incident rays so they appear to originate from a point on the same side as the light source, not concentrating them to a single point.
Option c: biconcave lens. A biconcave lens has both surfaces concave and similarly acts as a diverging lens, causing rays to spread apart rather than converge to a point.
Option d: both B and C. Since both concave and biconcave lenses diverge rays and do not converge to a single point, this combined option is incorrect for a converging requirement.
Summary: Only the convex lens option describes a lens that converges incident rays to a single point, whereas the other options describe lenses that diverge rays or mischaracterize the convergence behavior.
