"WitrynaUsing Newton’s rings, the refractive index of a liquid can be calculated. Let λa and λm represent the wavelength of light in air and in medium (liquid). If rn is the radius of the nth dark ring in the air and if rn is the radius of the nth dark ring in liquid, then rn2 = nRλa r`n2 = nRλm = nRλa/μ so, μ = rn2/ r`n2 fTHANK YOU Back to top About " - Newton rings experiment ppt
