What is the lens equation (write it down).
Imagine I give you a lens that focuses light coming from VERY far away into an image 10cm away from the lens. What is the DIOPTRIC power of this lens? Use the lens equation to figure this out. Draw a picture that shows the lens focusing light, label the distances, and show your work.
