John has placed an object 30 cm from a 20 cm converging lens. How far from the 20 cm converging lens should John placed a 10 cm converging lens that will function as the eyepiece.
Added by George H.
Step 1
First, we need to determine the focal length of the 20 cm converging lens. We can use the lens formula: 1/f = 1/do + 1/di where f is the focal length, do is the object distance (30 cm in this case), and di is the image distance. Since the object is placed beyond Show more…
