In a Newton's rings experiment, the radius of ring of the lens is 10.0m and its diameter is 5.0cm. Determine how many of that rings are produced

drwls,
Do you mean the RIM of the lens?
Does the lens really have a 10 METER diameter? I have never heard of a lens that large.
How can the diameter be less than the radius?
Please restate the problem more carefully
