After dropping a box containing converging lenses, an explorer needs to determine tAfter dropping a box containing converging lenses, an explorer needs to determine the focal length of each lens.
He places a bright flashlight 0.6 m from the lens such that the light shines through the lens. The image of the filament in the bulb is brought to a sharp focus on a sheet of paper held 0.2 m on the opposite side of the lens from the flashlight.
What is the focal length?
+ 0.6 m
- 0.2 m
+0.15 m
- 0.15 m
