Sir what more information do you need? This is complete question

6. (12 points) The interplanar spacing between the planes of Miller indices in hexagonal system is given by the following formula: d= 12 4 h+hk+k + 3 The lattice parameters are given by a = 0.942 nm and c = 0.588 nm. The XRD pattern of this material obtained with an xray of wavelength 0.1537 nm is shown below: hund 26 28 30 32 34 What are the Miller indices of the plane corresponding to the first major reflection and what is the interplanar separation between the planes giving rise to this reflection? Show your calculations. 6.
