Klaynos Posted January 22, 2007 Share Posted January 22, 2007 Or just use wikipedia (hyperphysics is also probably a good bet) http://en.wikipedia.org/wiki/Newton_rings They're not something I've ever really come accross though, so no more than that...

Meir Achuz Posted February 1, 2007 Share Posted February 1, 2007 what are newton rings????????????????????plz xplain They are interference bands that are seen when a large plano-convex lense (That is one side flat, the other spherical with a large radius) is placed on a flat glass plate, and a light of definite wave length is shone directly onto it. Destructive interference at every thickness of air space equal to (n+1/2)lambda produces dark rings. This is described in many physics texts, which still are available off line.
