A new optical method used in our lab to get clear fringes of interference use “He Ne laser” as a light source. These experiment construct firstly to avoid our need to sodium lamb, Secondly, a convex lens was used to obtain a large image fringes to make the parameters more accurate than using the real fringes, by using a new mathematical relationships, the wavelength was measured. The results were more accurate than the normal methods used.Downloads
