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

• Physics -

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
