Task 40328.

Installation for Newton´s Rings illuminated by monochromatic light incident normal to the surface of the plate. Monitoring is carried out in the reflected light. The radii of the two adjacent dark rings are rk = 4,0 mm and r (k + 1) = 4.38 mm. The radius of curvature of the lens R = 6,4 m. Find the sequence numbers of rings and the wavelength of incident light.
