EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.

and the sodium hydroxide. When using glassware in experiments‚ it must be flushed out to make sure that cross contamination does not happen and that the only thing that would then be coating the beaker is the distilled water. When all of the glassware has been cleaned‚ some sodium hydroxide should be placed in a plastic weighing boat next to the scales and place the second weighing boat on the scales and weigh it then click the on tare button to set it back to zero and weigh out 1g of sodium hydroxide
