A student carries out an experiment to investigate the relationship between the wavelength, Xand distance two consecutive bright fringe, x for monochromatic light. The studenl use doubleslit experiment. Firstly the student located an orange filter in front of single slii where iiswavelength, Xis 0.000590 mm. The distance between double slit and screen is arranged untilthe interference pattern observed. The experiment wasrepeated 4 times with yellow filter (X= 0.000570 mm), green filter (X = 0.000510 mm), cyan filter (X = 0.000475 mm) and violetfilter (X = 0.000400 mm). The result is shown on the graph x against X.
