Lesson: Convex Lenses Physics • 9th Grade
In this lesson, we will learn how to define a convex lens, describe the paths of light rays refracted through these lenses, and explain how rays are focused by such lenses.

Which of the objects shown in the diagram is a convex lens?
Light rays diverging from a point are incident on a convex lens, as shown in the diagram. Which of the other diagrams, (A), (B), (C), and (D), most correctly shows the directions of the rays that exit the lens?
Part of a convex lens is shown. No light rays pass through the lens, but several possible lines normal to the surface of the lens are shown.
Which line on the left-hand side of the lens is normal to the surface at the point that the line contacts the surface?
Which line on the right-hand side of the lens is normal to the surface at the point that the line contacts the surface?
