For the diffraction image below, the detector was positioned 200 mm from the crystal and the wavelength of x-rays was 1.5 what unit cell dimensions can be derived from the spacings of reflections within the central zone [(1,0,0), (0,10,)] on this diffraction image (a* = 1.75 mm [horizontal direction]; b* = 2.5 mm [vertical direction])? what is the unit cell dimension (c = ? ) parallel to the x-ray beam
