−< < + λ λ λ a m da . Rewriting this as −< < + da m da // we arrive at the result md a m max / < ≤+ 1. Due to the symmetry of the pattern, the multiplicity of the m values is 2 m max + 1 = 17 so that m max = 8, and the result becomes 89 <≤ d a where these numbers are as accurate as the experiment allows (that is, “9” means “9.000” if our measurements are that good). 80. The central diffraction envelope spans the range << + θ 11 where 1 1 sin ( / ).
