Part A: Wavelength of light by varying the location ofthe slits of double slit experiment Table 1 Analysis of light wavelength of green color Slit separation ' Wavelength measured, Cl: _ ??????".{?? : Separation Position of first Wavelength PD between between slits bright fringe calculated 1???? and screen y 1???? and D [ ] i l ????????? [l [l ' Find the calculated average wavelength lcal(avg) of the light? ' Compare [percent difference) 1631(avg) with actual wavelength? ' Make a graph between the position of the rst bright fringe on screen and the separation between slits and the screen. Fit the data with linear fitting and find the frequency of the light by using slope of the graph. ' Compare the wavelength of the light from the graph with the actual wavelength
