Unformatted text preview: diffraction of the light. Thus we should not see the lines overlapping as with each increase in the amount of slits the diffraction increases. Due to the decrease in overall slit width. We obtain average values of slit width to be about .00045mm for the 100 slit/mm, about .00015mm for the 300 slit/mm, and about .00004mm for the 600 slit/mm. As is shown on each graph you can see the equation of best fit for each data set....
