Lesson: Concave Lenses Physics • 9th Grade
In this lesson, we will learn how to define a concave lens, describe the paths of light rays refracted through these lenses, and explain how rays are focused by such lenses.
Sample Question Videos
Which of the points A, B, C, and D shown in the diagram is closest to the focal point of the concave lens?
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?
