diffraction grating

You should focus your discussion around coming your estimate of the wavelength of the laser to the actual wavelenght 632.8 nm. The following questions should be addressed in your discussion, with an explanation of your answers. 1. Which order m=1 to m=30 would you expect to have the greatest precision? Explain your answer. . Did you use all of the m=1 to m=30 measurements? Give your reasoning. . Is it valid to use the small angle approximation (i.e. 0 2 133.1109) 2 8111(9) answer. )? Justify you . How could you improve the precision and accuracy of your value of the wavelengt of the laser? In particular what measurements have the greatest inuence on the uncertainty
