## SparkNotes: Review of Optics: Multiple Choice Test on Optics

A converging lens is used to form an image on a screen. When the upper half of the lens is covered by an opaque screen. Answer: c Explaination: c because focal length of lens does not change but amount of light passing through lens becomes half.
