Aila is creating a model of a double convex lens. She draws horizontal lines to show light rays traveling toward the lens. How should Aila draw the light rays after they move through the lens?

• Aila should draw them converging to a point.

• Aila should draw them diverging without intersecting.

• Aila should draw them diffracting and moving upward.

• Aila should draw them continuing in the same direction.

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?

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

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

• 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 gathers bands of color together to form white light.

Which of these describes a concave lens?

• focuses light

• breaks light down into bands of color

• spreads light out

• reflects light

A model of a concave lens is shown below.

Which of the following describes a possible application of this type of lens?

• Concave lenses can be used in mirrors to make objects appear closer than they truly are.

• Concave lenses can be used in laser pointers to converge the projected light to a single point.

• Concave lenses can be used in microscopes to make small objects appear larger.

• Concave lenses can be used in car headlights to spread the projected light outwards.
