34. Installation for observation of Newton's rings is illuminated by monochromatic light with a wavelength λ = 0,6mkm normally incident. The space between the lens and the glass plate is filled with fluid, and viewed in transmitted light. The radius of curvature of the lens R = 4 m. To determine the refractive index n of the liquid, if the radius of the second ring light r2 = 1.8mm.
