Question

how to determine wavelength using newtons ring?
​

Answer 1

Answer:

• The wavelength λ of light is given by the formula: Where, Dn+m = diameter of (n+m)th ring, Dn = diameter of nth ring, m = an integer number (of the rings) R = radius of curvature of the curved face of the plano-convex lens.

Answer 2

Answer:

Formula used : The wavelength λ of light is given by the formula: Where, Dn+m = diameter of (n+m)th ring, Dn = diameter of nth ring, m = an integer number (of the rings) R = radius of curvature of the curved face of the plano-convex lens.
