To determine the wavelength of sodium light by Newton's ring. 2. Plot a graph between 'n' and 'D n 2' in the case of Newton's rings and hence find the radius of curvature of the surface of the lens Apparatus Required : A plano-convex lens of large radius of curvature, optical arrangement for Newton's rings, plane

Newton's Rings 24 Discussion (i) The Newton's ring experiment can be also used to find the wavelength of a monochromatic light. In this case, the radius of curvature of the convex surface of the given lens is supplied or is determined otherwise. By employing sodium light whose mean wavelength is 5893 Å, R can be

Newton ring's experiment. Procedures: 1. At first unzip "Newton's rings_vle (zipped)" File. Click on the executable file "Newton's rings_vle", then a window will open as shown in Fig. 3. 2. The default option for the source of light is red. Select the yellow color of light by moving

all of the rings. For this reason differences in r are less dependent on the force of contact between the surfaces than are individual values of r. Consider the bright ring with m = n. For this ring we have the equations R d t n n 8 2 = and ⎟λ ⎠ ⎞ ⎜ ⎝ ⎛ = + 2 1 2 n t n. Now, consider the bright ring with m = n + k. For this ring we ...
