- Did you notice that the image of the object on the opposite side of the lens from the actual object was upside down? Why is this so?
-
Why do you think increasing the curvature radius of the lens changes the location of the image?
-
How do you think a change in the refractive index of the lens changes the path of light rays through the lens?
-
What would happen to the image of the object if the top half of the lens were covered up? (Hint: try making the lens larger and smaller in diameter)
-
Use the interactive activity to explain how magnifying lenses and eyeglasses work.
