powder cristal method
when crystalline substance is available in the form of very small crystals or in powder fprm. this technique is also known asdebye _sherrer the crystalline substance be finely grounded and powdered so that its tiny crystals are randomly oriented.the powerder specimen c stuck on hair by means of gum and placed in the path of a narrow monochromatice x-ray
2hence reflected x-ray add up to give the resulting reflection strong
crystal and ionization chamber has moved becomes twice the angle Tthrough which the crystal has rotated
az two rays have travelled the same distance from point a and n onwards
it is due to the preseence of such sets of parallel planes that a crystal acts as reflection grating
ii the separation between lines corresponding to two near wavelengths increases with the orer of the spectrum
