In this worksheet, we will practice defining a concave lens, describing the paths of light rays refracted through it, and explaining how rays are focused by such lenses.
At which of the points A, B, C, and D shown in the diagram is the angle of refraction greatest?
Which of the following diagrams correctly shows the paths of light rays exiting a concave lens if the light rays enter the lens parallel to the axis of the lens?
Which of the objects shown is a concave lens?
Light rays converging to a point are incident on a concave lens, as shown in the diagram. Which of the other diagrams (A), (B), (C), (D), most correctly shows the directions of the rays that exit the lens?
