A student must create a mode of a lens. The lens must be able to focus light into a small space. Which best describes the type of lens the student should model?

A. The student should model a convex lens because it gathers bands of color together to form white light.

B. The student should model a convex lens because it directs light toward the center of the lens.

C. The student should model a concave lens because it directs light toward the center of the lens.

D. The student should model a concave lens because it gathers bands of color together to form white light.

The student should model a convex lens because it directs light toward the center of the lens.(B)

Explanation:

Optical devices that work on the principle of refraction are called Lenses.

Their are two type of lenses:

Convex lenses are those lenses that  are curved outward at their center,  the rays of light coming from infinite distance are all focused into a point of the lens, called Principal focus. Therefore, a convex lens directs lights towards a point.

So the answer of the above question is (B)  The student should model a convex lens because it directs light toward the center of the lens.
