Problem

A synchrotron beamline illuminates a protein crystal with X-rays of wavelength λ=0.98 A˚\lambda = 0.98\,\mathrm{\mathring A}. The detector records Bragg spots out to a largest scattering angle 2θmax⁡=60∘2\theta_{\max} = 60^\circ. Using dmin⁡=λ/(2sin⁡θmax⁡)d_{\min} = \lambda/(2\sin\theta_{\max}), find the resolution dmin⁡d_{\min} of this data set.
