There was a margin of error while conducting this experiment that caused us to get a different value for the wavelength other than the theoretical value of 0.6328[um]. This uncertainty comes from the inability to measure more accurately the displacement of the zero order to the first orders, which was equal to Â±0.05[cm]. 4...
